AD 98-13-38 Amendment 39-10629

This amendment adopts a new airworthiness directive (AD), applicable to certain British Aerospace (Jetstream) Model 4101 airplanes, that requires installation of a warning placard for the fire extinguisher exhaust port located in the rear baggage bay. 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 blockage of the fire extinguisher exhaust port, which could result in reduced fire protection in the rear baggage bay and consequent injury to the passengers and crewmembers.
