Summary
We propose to rescind an airworthiness directive (AD) for the products listed above. The existing AD resulted from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
On several occasions, leaks of the landing gear emergency blowdown bottle have been reported. Investigations revealed that the leakage was located on the nut manometer because of a design deficiency in the bottle head. If left uncorrected, the internal bottle pressure could not be maintained to an adequate level and could result in a malfunction, failing to extend landing gears during emergency situations.
Since issuance of that AD, we have determined that the condition is not unsafe. This proposed action to rescind the AD would allow the public the opportunity to comment on the FAA's determination of the condition being unsafe beforeit is officially rescinded.
