NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Require operators of Bell 407 helicopters to conduct subsequent torque checks of the tail boom attachment hardware and visual inspection of the tail boom attachment fittings as referenced in Safety Recommendation A-22-28 at an interval significantly less than the currently required interval to provide multiple opportunities for detecting any improperly installed or fractured attachment hardware or fittings. Require operators to report findings to the FAA. (Urgent)
In plain language (FlightFinder summary)
The FAA is asked to mandate that Bell 407 helicopter operators perform torque checks and visual inspections of tail boom attachment hardware and fittings more frequently than current requirements, and to report any findings. This repeated checking aims to increase the chances of detecting improperly installed or fractured components.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
