Lufthansa Technik (LHT) is studying ways to reduce the loads imposed on a bizliner’s interior walls and their structural attachments by a sudden drop in cabin pressure. The solution appears to lie in installing large cutouts in the walls and floor.
Ever since two pilots fell asleep in the cockpit of a Bombardier CRJ operating as Go! Flight 1002 during a February 2008 flight from Honolulu to Hilo, Hawaii, the NTSB has urged the FAA to tackle the issue of obstructive sleep apnea (OSA) among pilots. The captain of that aircraft was diagnosed with severe OSA after the flight.
By the time hypoxia is detected, it’s often too late, and the higher the cabin altitude, the less time pilots have to realize that they need to don oxygen masks.
The FAA has issued an airworthiness directive for the Boeing 737-600, -700, -700C, -800, and -900 series. The AD was prompted by a report of cracks found in the skin at body station 540 just below stringer S-22L on a 737-700.
The National Transportation Safety Board (NTSB) has concluded that the improper installation of a fuselage crown skin panel during the manufacturing process was the probable cause of substantial damage to a Southwest Airlines Boeing 737 during a rapid decompression incident in April 2011.
While the U.S. government is on a Congress-created enforced shutdown, the aviation industry might be tempted to wonder what the FAA actually accomplishes. What we are learning is that a lot of what the FAA does is process paperwork. And when the paperwork stops flowing, we can be forced to stop flying.
Student pilot Michael Graham pleaded guilty in a North Carolina U.S. District Court on May 6 to falsifying statements in connection with his submission of an FAA medical form to obtain his student pilot certificate. According to an FAA statement, Graham did not disclose his criminal or medical history or current medications on his application for an airman medical certificate, which an aviation medical examiner subsequently approved. The FAA was notified after his flight instructor became concerned about Graham’s behavior.
LouElla Hollingsworth, a veteran air traffic controller with 29 years’ experience, saved the pilot of a Piaggio Avanti when she recognized signs of hypoxia in his radio transmissions on November 16 last year. Thanks to Hollingsworth’s quick thinking as a Fort Worth Center controller in Texas, she convinced the pilot to descend to a lower altitude where the oxygen level was suitable for breathing.
There is only a little time left to comment on a petition for exemption from the third-class medical requirement for pilots flying recreationally. The exemption petition was submitted to the FAA by the Experimental Aircraft Association and the Aircraft Owners and Pilots Association, and the comment period closes on July 2. As of June 25, there were more than 3,300 comments, but the more comments received, the more the FAA might pay attention.
The U.S. Air Force approved a resumption of flight operations by the Lockheed Martin F-22 Raptor, ending a four-month standdown ordered after pilots experienced symptoms of hypoxia. The suspected source of the problem, the aircraft’s onboard oxygen generation system (Obogs), remains under study.
