AD/J4100/17 - Nose Fuselage Structure between Station 4 and Station 11

This Airworthiness Directive requires operators of all BAe Jetstream 4100 series aeroplanes to inspect the nose fuselage between station 4 and station 11 and carry out repairs following BAE Mandatory Service Bulletin J41‑53‑047 (or a later CAA/EASA‑approved revision). The first inspection must be done within 30 days after 20 February 2008 unless already completed, and repeated at intervals not exceeding 6,000 landings; it became effective 20 February 2008. It was issued after diaphragm damage was found in service and places inspection and repair costs and duties on operators (Requirement; Compliance; Background).
