Applicability: Model 400A airplanes having serial numbers RK-1 through RK-57 inclusive, RK-59, RK-60, and RK-62 through RK-66 inclusive; and Model 400T airplanes having serial numbers TT-02 through TT-30 inclusive, and TT-32; certificated in any category.

Compliance: Required as indicated, unless accomplished previously.

To prevent reduced structural capability of the airframe, accomplish the following:

(a) Within 200 hours time-in-service after the effective date of this AD, inspect the rivets in the escape hatch substructure to verify that the proper rivets are installed in accordance with Beechcraft Service Bulletin 2509, dated July 1993.

(1) If the rivet is part number (P/N) MS20470E6, no further action is required by this AD.

(2) If the rivet is not P/N MS20470E6, prior to further flight, replace the rivet with a new Cherry Max rivet or a HI-LOK fastener, in accordance with Beechcraft Service Bulletin 2509, dated July 1993.

(b) As of the effective date of this AD, no person shall install any rivet having P/N MS20470AD5 in the location shown in Figure 1 of Beechcraft Service Bulletin 2509, dated July 1993, on any airplane.

(c) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Wichita Aircraft Certification Office (ACO), FAA, Small Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Wichita ACO.

NOTE: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Wichita ACO.

(d) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate the airplane to a location where the requirements of this AD can be accomplished.

(e) The inspection and replacement shall be done in accordance with Beechcraft Service Bulletin 2509, dated July 1993. (NOTE: The issue date of Service Bulletin 2509 is indicated only on page 1 of the document; no other page of this document is dated.) This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR Part 51. Copies may be obtained from Beech Aircraft Corporation, P.O.
