The FAA proposes to issue an airworthiness directive for certain variants of the Bombardier CL-600, 601 and 604.
The FAA has issued a Final Rule amendment superseding an existing airworthiness directive for specified Eurocopter AS350s and AS355s with certain tail-rotor pitch-control rods installed.
Estero, Fla.-based Flightdocs, a provider of aircraft maintenance tracking software and services, released on Monday what it says is the first aircraft maintenance tracking iPad application. The Flightdocs Mobile Information Center app is available free at the iTunes store, though a Flightdocs maintenance tracking subscription is required.
The FAA has issued an Airworthiness Directive for the Gulfstream Aerospace Galaxy and Gulfstream 200, citing cracked nuts found on the aircraft’s production line during routine post-assembly inspection. Investigation revealed that the cracks resulted from hydrogen embrittlement combined with high hardness.
The FAA has issued new and revised guidance to the aviation industry regarding development and implementation of Airworthiness Directives (ADs). Details on the new guidance were published in an FAA Special Airworthiness Information Bulletin (SAIB NM-11-53).
Effective yesterday, an EASA Airworthiness Directive (AD) has restored the full original flight envelope for the Dassault Falcon 7X, providing the fly-by-wire control system is updated. Dassault has developed a modification of the system to improve “the monitoring and reversion logic of the horizontal stabilizer trim system,” EASA said.
The EASA today grounded the Dassault Falcon 7X, via an emergency Airworthiness Directive, following a runaway pitch trim event experienced in one of the trijets yesterday during descent. According to the EASA, the crew successfully recovered the aircraft to a stable flight profile and performed an uneventful landing.
The FAA is seeking comments on a proposed legal interpretation of Airworthiness Directive (AD) regulations. The interpretation comes from the FAA’s Organization/Procedures Working Group of the Airworthiness Directive Implementation Aviation Rulemaking Committee (ARC). Issues identified by the ARC are mostly a result of the FAA’s 2002 plain-language revision of 14 CFR Part 39, which governs the AD process.
One of the problems with the aviation rulemaking committee (ARC) process is that it gives people, and especially FAA lawyers, too much time to think. And too much thinking often leads to onerous interpretations of what seem like simple regulations.
India’s civil aviation authority, the DGCA, is considering grounding all civil Hindustan Aeronautics Limited (HAL) Dhruv light twin helicopters until the airframe is modified around the intermediate gearbox (IGB) in the tailfin. In some helicopters, “Cracks were observed on the rib bottom of the IGB and the associated area of the fin torsion box assembly,” according to a recently proposed Airworthiness Directive.
