Applicability: Model 400A series airplanes having serial numbers RK-1 through RK-28, inclusive; certificated in any category.

  (a) Within 14 days after the effective date of this AD, conduct a one-time visual inspection of the flame arrestor filter, Beech part number 45A48235-3, to determine whether it is manufactured of aluminum honeycomb (silver-colored) or phenolic honeycomb (brown-colored) material, in accordance with Beech Service Bulletin 2445, dated June 1992.

  (1) If the filter is made of aluminum honeycomb material, no further action is required.

  (2) If the filter is made of phenolic honeycomb material, prior to further flight, replace the currently installed flame arrestor filter with one having Beech part number 45A48235-5, or with Beech part number 45A48235-3 that has been confirmed to be made of aluminum.

  (b) As of the effective date of this AD, no flame arrestor filter, Beech P/N 45A48235-3, constructed of phenolic honeycomb material shall be installed 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.
