Action
Notice of proposed rulemaking (NPRM).
Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain De Havilland Aircraft of Canada Limited Model DHC-8-400, - 401, and -402 airplanes. This proposed AD was prompted by a report of cracking found on a main landing gear (MLG) drag strut assembly. This proposed AD would require a records review to determine if an affected MLG drag strut assembly is installed, repetitive detailed inspections for cracking of affected strut assemblies, a one-time magnetic particle inspection for cracking, and on-condition actions if necessary. The FAA is proposing this AD to address the unsafe condition on these products.
