What this AD requires

This amendment revises Airworthiness Directive (AD) 97-15-13 R1, which currently requires installing lubrication fittings in the airstair door handle and latch housing mechanisms on certain Raytheon Aircraft Company (Raytheon) Beech Models 1900, 1900C, and 1900D airplanes. Since issuance of AD 97-15-13 R1, Raytheon has revised the applicable service information to correct the reference to the number of parts each owner/operator of the affected airplanes should order and to change an incorrect reference to a maintenance manual. This AD retains the actions of AD 97-15-13 R1, and incorporates the revised service bulletin into the AD. The actions specified by this AD are intended to continue to prevent moisture from accumulating and freezing in the airstair door handle and latch housing, which could result in the door freezing shut and passengers not being able to evacuate the airplane in an emergency situation.

Boilerplate applicability only; a broader model/serial-number list precedes this excerpt, though the text directly names affected Beech Model 1900D airplanes. Requires installing lubrication fittings in the airstair door handle and latch housing per Raytheon Mandatory Service Bulletin No. 2572 (July 1996) / SB.2572 Rev. 1 (May 1998), to prevent the door from freezing shut and blocking emergency evacuation.

Whether AD 99-9250 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Is AD 99-9250 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
