AD 2001-03-12 66 FR 10953 Active

This amendment supersedes an existing airworthiness directive (AD), applicable to all British Aerospace (Jetstream) Model 4101 airplanes, that currently requires repetitive inspections to detect loose or migrated levers of the elevator cable tension regulators, and replacement of the regulator assembly with a new assembly, if necessary. This amendment requires modification of the elevator cable tension regulator lever assembly, terminating the repetitive inspections. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent the elevator cable tension regulator from becoming detached from the splined shaft of the assembly, which could result result in difficulty adjusting the elevators, leading to reduced controllability of the airplane.
