The National Transportation Safety Board (NTSB), the agency responsible for investigating transportation accidents in the United States, released updates on three major investigations on June 14.

The NTSB, well known publicly for its involvement in the investigation of aviation incidents which involve harm or loss of human life, is also an agency that oversees the transportation of refined petroleum and gas products, chemicals and minerals.

The agency determined the cause of a natural gas pipeline explosion that killed six. It also detailed the cause of an accidental release of 204,000 gallons of anhydrous ammonia from a pipeline in an environmentally sensitive area, and released preliminary information involving two commercial aircraft coming within 30-50 feet of each other on a runway.

In the gas explosion disaster, the towing vessel Miss Megan, which was of specifications that did not require inspection by the United States Coast Guard, was being operated in the West Cote Blanche Bay oil field in Louisiana by Central Boat Rentals on behalf of Athena Construction on October 12, 2006. The Miss Megan was pushing barge IBR 234, which was tied along the starboard side of barge Athena 106, en route to a pile-driving location. Athena Construction did not require its crews to pin mooring spuds (vertical steel shafts extending through wells in the bottom of the boat and used for mooring) securely in place on its barges and consequently this had not been done. During the journey, the aft spud on the Athena 106 released from its fully raised position. The spud dropped into the water and struck a submerged, high-pressure natural gas pipeline. The resulting gas released ignited and created a fireball that engulfed the towing vessel and both barges. The master of the towing vessel and four barge workers were killed. The Miss Megan deckhand and one barge worker survived. One barge worker is officially listed as missing.

The NTSB blames Athena Construction for the disaster, citing in the final report that Athena Construction’s manual contained no procedures mandating the use of the safety devices on the spud winch except during electrical work. It was found that if the Athena 106 crew had used the steel pins to secure the retracted spuds during their transit, a pin would have prevented the aft spud from accidentally deploying. Furthermore, the spud would have remained locked in its lifted position regardless of whether the winch brake mechanism, the spud’s supporting cable, or a piece of connecting hardware had failed.

The NTSB also found that contributing to the accident was the failure of Central Boat Rentals to require, and the Miss Megan master to ensure, that the barge spuds were securely pinned before getting under way. The Board noted that investigators found no evidence that the Miss Megan master or deckhand checked whether the spuds had been properly secured before the tow began. While Central Boat Rentals had a health and safety manual and trained its crews, the written procedures did not specifically warn masters about the need to secure spuds or other barge equipment before navigating. The NTSB stated that the company’s crew should have been trained to identify potential safety hazards on vessels under their control.

NTSB Chairman Mark Rosenker said of the investigation’s results, “Having more rigorous requirements in place could have prevented this accident from occurring. Not only do these regulations need to be put in place but it is imperative that they are enforced and adhered to.”

The NTSB has made a number of safety recommendations as a result of this accident and the subsequent investigation. Recommendations were made to Athena Construction and Central Boat Rentals to develop procedures and train the employees of its barges to use the securing pins to hold spuds safely in place before transiting from one site to another.

The most major of the other recommendations are:

To the Occupational Safety and Health Administration:

• Direct the Maritime Advisory Committee for Occupational Safety and Health to issue the following documents document to the maritime industry: (1) a fact sheet regarding the accident, and (2) a guidance document regarding the need to secure the gear on barges, including spud pins, before the barges are moved, and detailing any changes to your memorandum of understanding with the Coast Guard.

To the U. S. Coast Guard

• Finalize and implement the new towing vessel inspection regulations and require the establishment of safety management systems appropriate for the characteristics, methods of operation, and nature of service of towing vessels.
• Review and update your memorandum of understanding with the Occupational Safety and Health Administration to specifically address your respective oversight roles on vessels that are not subject to Coast Guard inspection.

The NTSB also released the result of its investigation into an environmental disaster in Kansas on October 27, 2004 in which 204,000 gallons (4,858 barrels) of anhydrous ammonia was spilled from a ruptured pipeline in Kingman into an environmentally sensitive area. Chemicals from the pipeline entered a nearby stream and killed more than 25,000 fish, including some fish from threatened species.

The incident reached the scale that it did due to operator error after the initial rupture. The 8 5/8-inch diameter steel pipeline, which was operated by Enterprise Products Operating L.P., burst at 11:15 a.m. in an agricultural area about 6 miles east of Kingman, Kansas. A drop in pipeline pressure, indicating abnormal conditions or a possible compromise in pipeline integrity, set off alarms displayed on the computerized pipeline monitoring system. Shortly after the first alarm the pipeline controller, in an attempt to remedy the low pressure, increased the flow of anhydrous ammonia into the affected section of pipeline. A total of 33 minutes elapsed between the time when the first alarm indicated a problem with the pipeline and the initiation of a shutdown.

In its initial report to the National Response Center (NRC), the pipeline operator’s accident reporting contractor reported a release of at least 20 gallons of ammonia, telling the NRC that an updated estimate of material released would be reported at a later time. No such report was ever made. Because of the inaccurate report, the arrival of representatives from the Environmental Protection Agency was delayed by a full day, affecting the oversight of the environmental damage mitigation efforts.

The cause of the rupture itself was determined to be a pipe gouge created by heavy equipment damage to the pipeline during construction in 1973 or subsequent excavation activity at an unknown time that initiated metal fatigue cracking and led to the eventual rupture of the pipeline.

“We are very fortunate that such highly toxic chemicals of the size and scope involved in this accident were not released in a populated area,” commented Rosenker. “Had this same quantity of ammonia been released near a town or city, the results could have been catastrophic.”

As a result of this accident, the NTSB made the following safety recommendations:

To the Pipeline and Hazardous Materials Safety Administration:

• Require that a pipeline operator must have a procedure to calculate and provide a reasonable initial estimate of released product in the telephonic report to the National Response Center.
• Require that a pipeline operator must provide an additional telephonic report to the National Response Center if significant new information becomes available during the emergency response.
• Require an operator to revise its pipeline risk assessment plan whenever it has failed to consider one of more risk factors that can affect pipeline integrity.

To Enterprise Products Operating L.P.:

• Provide initial and recurrent training for all controllers that includes simulator or noncomputerized simulations of abnormal operating conditions that indicate pipeline leaks.

“The severity of this release of dangerous chemicals into the community could have been prevented,” said Rosenker. “The safety recommendations that we have made, if acted upon, will reduce the likelihood of this type of accident happening again.”

As well as concluding their investigation of the above accidents, the NTSB also released preliminary information regarding a serious runway incursion at San Francisco International Airport between two commercial aircraft on May 26, 2007.

At about 1:30 p.m. the tower air traffic controller cleared SkyWest Airlines flight 5741, an Embraer 120 arriving from Modesto, California, to land on runway 28R. Forgetting about the arrival airplane, the same controller then cleared Republic Airlines flight 4912, an Embraer 170 departing for Los Angeles, to take off from runway 1L, which intersects runway 28R.

After the SkyWest airliner touched down, the Airport Movement Area Safety System (AMASS) alerted and the air traffic controller transmitted “Hold, Hold, Hold” to the SkyWest flight crew in an attempt to stop the aircraft short of runway 1L. The SkyWest crew applied maximum braking that resulted in the airplane stopping in the middle of runway 1L. As this was occurring, the captain of Republic Airlines flight 4912 took control of the aircraft from the first officer, realized the aircraft was traveling too fast to stop, and initiated an immediate takeoff. According to the crew of SkyWest 5741, the Republic Airlines aircraft overflew theirs by 30 to 50 feet. The Federal Aviation Administration has categorized the incident as an operational error.

The NTSB sent an investigator to San Francisco, who collected radar data, recorded air traffic control communications, and flight crew statements, and interviewed air traffic control personnel prior to the NTSB making the preliminary release.

An exhausted Charles Kennedy returned to the election campaign to launch a twenty page Liberal Democrat manifesto targeted at disaffected Labour voters, promising a fairer tax system and withdrawal from Iraq.

Entitled The Real Alternative the manifesto pledges to reduce the lowest rate of income tax, but increase the rate on those earning over £100,000 to 50%. The party would also scrap the unpopular local council tax in favour of a new local income tax. The manifesto also promises to remove hidden “stealth taxes”.

Under this system the party claims the poorest 15 million (25%) of people in Britain would be better off, and the middle 50% would be paying no extra tax.

The manifesto promised to scrap the controversial university tuition fees, increase services for pensioners and add £100 a month to the state pension, and train 21,000 new primary school teachers and 10,000 new police. A Lib Dem government would make eye and dental checks free, and reduce the cost of prescription medicine.

The Liberal Democrats were the only one of the three largest parliamentary parties to have consistently voted against the Iraq war, and the manifesto has promised an exit strategy with a phased withdrawal of Britain’s 8,000 troops still in the country.

“We reject a foreign policy based on ‘my ally right or wrong’,” Kennedy said. “And we say that war should always be a last resort.”

Kennedy, who became a father on Tuesday, admitted he’d had little sleep before the manifesto launch, and stumbled while answering questions on the proposed tax system.

The Associated Press (AP) reported on Tuesday the U.S. Secret Service is conducting drone exercises over Washington, D.C. to defend against unmanned aerial vehicles being flown over the area.

The Federal Aviation Administration (FAA) approved the Secret Service to conduct these flying exercises. The exercises are to be over parts of D.C. airspace which is normally off-limits below 18,000 feet, also called a no-fly aone or the D.C. flight restricted zone. The exercises are to take place in the very early morning hours over the next several weeks.

According to AP, a U.S. official speaking under condition of anonymity said the agency is testing these drones for law enforcement and to defend against potentially dangerous drones, but declined to comment on the specific details because they’re classified. However, they sought to prevent concerns by possible witnesses by publicizing their intent to conduct tests. The agency is cautious of witnesses of unmanned aerial vehicles flying over D.C. because of a drone sighting incident several weeks ago. Witnesses saw several unidentified drones flying over Paris, France, which caused concerns.

AP said techniques to be tested include signal jamming. Most drones use radio-frequency signals for remote control. Intercepting these signals might allow tracking the drones. Jamming, though, could interrupt Wi-Fi of people in the vicinity.

The FAA last month announced preliminary guidelines requiring UAVs be operated within sight of the operator, prohibiting night flying, and requiring speeds below 100 miles per hour (about 160 kph) and altitudes below 500 feet.

Adam Aircraft Industries has laid off 300 members of its 800-strong workforce and suspended operations at their plant in Ogden, Utah. The moves come as the result of unexpected financial difficulties.

In addition, Adam is transferring much of its work at Pueblo, Colorado to its headquarters at Centennial. The only operations that are to continue in Pueblo is machine shop work. In addition to these three locations, Adam had previously been considering the possibility of a plant at New Mexico.

Fifty employees were laid off at the Ogden facility, 170 in Pueblo and 80 in Centennial. Ogdon is planned to remain inoperational for six months. Laid off workers may be able to obtain new positions within the company when production resumes.

Adam Aircraft are producing two carbon composite aircraft: the Adam A500 twin-engine piston aircraft, which is certified and due to enter full production soon, and the Adam A700 very light jet, which is undergoing US federal certification processes.

Adam Aircraft spokesperson Shelly Simi said that the company is looking for between US$75 million and $100 million, and that they are in talks with Citibank to secure these funds.

Adam secured $93 million in August 2006, and $105 million in June 2007. The A500 is valued at $1.2 million and the A700 at $2.5 million. Seventeen A500s have been manufactured, of which seven have been delivered to customers. The backlog of orders totals around $1 billion.

Adam Aircraft President Duncan Koerbel released a statement that said To provide for our future growth, we must be strategic in our focus by managing current cash expenditures to ensure adequate time to secure financing for the long term. We’re off to a good start in this effort with assistance from our partner, Citibank, but we need to be able to provide them with sufficient time working with potential investors to secure long term financing.”

MTV‘s 2005 Video Music Awards were rather unbalanced this year, with Green Day’s capture of seven of the eight awards for which they were nominated. The awards were for their single “Boulevard of Broken Dreams” off of the American Idiot album. Up-and-coming rock bands Fall Out Boy and The Killers also won awards. Kelly Clarkson came out with two awards.

The event was hosted by Sean “Diddy” Combs at the American Airlines Arena in Miami, Florida, USA, which was unaffected by the passing of Hurricane Katrina through the area or by the shooting of rap producer “Suge” Knight.

Some notable events was Combs “conducting” a string orchestra in memory of slain rapper Notorious B.I.G while his song played, fellow rapper Snoop Dogg came out to sing the last verse of B.I.G’s hit song “Warning”.

Green Day arrived at the event in their rusted green convertible from the Holiday and Boulevard of Broken Dreams music videos. They kicked off the show with a performance of Boulevard of Broken Dreams.

R. Kelly performed a new segment to his soap opera song “Trapped In The Closet”. Kelly remains a chart-topper even though the star is awaiting trial for child pornography charges.

Marion “Suge” Knight was shot in the leg at a private party, hosted by Kanye West, at the Shore Club Saturday night, one day before the main event. He was taken to nearby Mount Sinai Hospital where he was treated for the non-lethal gunshot wound.
