NTSB Safety Recommendation — Aviation

Recommendation text

AS A RESULT OF THESE TWO ACCIDENTS THE BOARD RECOMMENDS THAT AD 67-19-1 BE AMENDED TO REQUIRE REMOVAL OF THE TERSION STRAP ASSEMBLIES AT A SELECTED TIME IN SERVICE BASED ON THE INDICATED FAILURE LIFE IN THE MOST RECENT ACCIDENT OF 242 HOURS AND THAT BRANTLY SERVICE LETTER 305-67-3 BE MADE MANDATORY AT SOME INTERVAL CONSIDERABLY LESS THAN THE PRESENTLY SPECIFIED 80 HOURS UNTIL SERVICE EXPERIENCE INDICATES A PROVEN INTERVAL EXTENSION.

In plain language (FlightFinder summary)

The NTSB urges the FAA to make a manufacturer’s service bulletin mandatory at intervals shorter than the current eight hours until safety data supports longer periods. This action is intended to ensure that tension strap assemblies are removed from aircraft before they reach their demonstrated failure point of 242 hours in service. The goal is to prevent accidents caused by these components failing due to wear and tear.

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.
