✈️New FAA Airworthiness Directive for Leonardo Helicopters Compliance
The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model AB139 and AW139 helicopters. This AD was prompted by reports of broken main landing gear (MLG) shock absorber piston rod eye ends. This AD requires repetitively inspecting the MLG shock absorber piston rod eye ends, reporting the results of the inspection, and, depending on the results, replacing the MLG shock absorber assembly. It also prohibits installing certain MLG shock absorber assemblies unless specific requirements are met, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

This document revises the chest jacket and spine box specifications for the Hybrid III 5th Percentile Female Test Dummy (HIII-5F). The jacket revisions resolve discrepancies between the jacket specifications in subpart O and jackets available in the field, and ensure a sufficiently low level of variation between jackets fabricated by different manufacturers. The spine box revisions eliminate a source of signal noise caused by fasteners within the box that may become loose during sled or vehicle crash tests. This rulemaking responds to a petition for rulemaking from the Alliance of Automobile Manufacturers.
