Mid-Continent Instruments has received an approved model list (AML) supplemental type certificate (STC) from the FAA for its MD835 lithium emergency power supply. The award is the first FAA Part 23 approval for a lithium nanophosphate battery through the AML STC process. Thirty aircraft are included in the STC, including the King Air 90, 200 and 300 series, Beech 1900, Beech Premier and Cessna Citation 501, 525A/B.
Bell 206L-3, Abilene, Texas, March 29, 2009–The NTSB determined the fatigue crack in the trailing edge of a main rotor blade was caused by interconnected porosity and resulting corrosion resulting from an undetected manufacturing defect. During a post-flight inspection following a flight in turbulence, the pilot noted the crack in the blade.
The FAA has become sufficiently concerned about maintenance technician fatigue to take proactive measures to educate the maintenance community. The agency’s maintenance fatigue Web site (https://hfskyway.faa.gov/HFSkyway/FatigueTool.aspx) provides information on fatigue issues and tools to help technicians and management address fatigue risk.
There are “tens of thousands of aging military aircraft” flying with the world’s air forces and many of those aircraft are more than 25 years old, according to Rob McDonald, ASIS marketing director. “Many of these fleets are set to be still flying in 20 years or more, with some aircraft, such as the USAF KC-135 tankers, topping 80 years old before the last aircraft is withdrawn from service,” he said.
With military aircraft are working harder and longer, the task of managing their service life safely and cost efficiently is becoming ever more critical. This has prompted Ultra Electronics Controls to conceive the ASIS aircraft structural integrity system, providing an innovative approach to monitoring and maintaining them.
While it seems that most of the focus on fatigue issues is on pilots, the FAA is concerned about maintenance technician fatigue and has taken steps to educate the maintenance community. One excellent resource is the agency’s maintenance fatigue Web site, which offers information on fatigue issues and tools to help technicians and company leadership manage fatigue risk.
Loss of engine power during landing approach due to a fatigue fracture in a power turbine blade caused the fatal helicopter crash, according to the Board. N67GE, operated by Island Express Helicopters, was landing on Santa Catalina Island at the end of a Part 135 flight from Long Beach when witnesses heard a “pop” sound and saw flames emanating from the back of the engine. The helicopter then crashed and was consumed by fire.
Yesterday the NTSB released the finding of the cause of the May 24, 2008, Island Express helicopter accident in Two Harbors, Avalon, on Catalina Island, in California. The Eurocopter AS350D collided with terrain while landing after a flight from the Queensway Bay Heliport, Long Beach, Calif.
The so-called “smart cabin automated dimming system” (Scads) marks the latest stage in evolution of the electrically dimmable E-Shade smart window from InspecTech of Fort Lauderdale.
Midcoast Aviation has expanded its capability to assist aircraft operators at their home bases to supplement in-house maintenance staff. “We have been providing this select service to customers by request for years,” said Morris Smith, director of technical services. “Because operators have found the service so beneficial it just made sense to expand and let all our customers know mobile maintenance teams are available to come to them.
