AD 2001-17—15 Honeywell International Inc.: Amendment 39-12406. Docket No. 94-ANE-38-AD. Supersedes AD 95-09-02, Amendment 39-9206.

Applicability: This airworthiness directive (AD) is applicable to Honeywell International Inc. (formerly AlliedSignal Inc. and Textron Lycoming Inc.) LTS101-600A-2, -600A-3 and -600A-3A series turboshaft and LTP101-600A-1A, -700A-1A series turboprop engines incorporating Chandler Evans Company (CECO) engine fuel pumps, part numbers (P/N's) 4-301-128-01, -02, -03, -04, -05, -06, -07, -08, -09, and -10 and -11. These engines are installed on but not limited to the following single-engine aircraft: Eurocopter France (formerly Aerospatiale) AS350D series helicopters and Airtractor AT302, Pacific Aero 08-600, and Page (Ayres S-2R) Thrush series airplanes. This AD is not applicable to engines installed on twin-engine aircraft.

Note 1:

This AD applies to each engine identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For engines that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (h) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

Required as indicated, unless accomplished previously.

To prevent engine fuel pump failure, which can result in total engine power loss and possible loss of the aircraft, accomplish the following:

(a) Remove from service and return to CECO for inspection, engine fuel pumps with greater than 751 hours time-in-service (TIS), but less than 900 hours TIS since new, overhaul, or time since last inspection on the effective date of this AD, within the next 100 hours TIS after the effective date of this AD, in accordance with AlliedSignal Service Bulletin (SB) LT 101-73-20-0203, dated August 18, 1999, or Honeywell International Inc. SB LT 101-73-20-0203, Revision 1, dated January 5, 2001.

(b) Remove from service and return to CECO for inspection, engine fuel pumps with greater than 451 hours TIS, but less than or equal to 750 hours TIS since new, overhaul, or time since last inspection, on the effective date of this AD, within the next 150 hours TIS after the effective date of this AD, in accordance with AlliedSignal SB LT 101-73-20-0203, dated August 18, 1999, or Honeywell International Inc. SB LT 101-73-20-0203, Revision 1, dated January 5, 2001.

(c) Remove from service and return to CECO for inspection, engine fuel pumps with less than or equal to 450 hours TIS, but less than 600 hours TIS since new, overhaul, or time-since-last-inspection on the effective date of this AD, within the next 150 hours TIS after the effective date of this AD, whichever occurs first, in accordance with AlliedSignal SB LT 101-73-20-0203, dated August 18, 1999, or Honeywell International Inc. SB LT 101-73-20-0203, Revision 1, dated January 5, 2001.

(d) The time since last inspection in compliance with AD 95-09-02 may be applied to satisfy the inspection time requirements of (a), (b), and (c).

(e) Thereafter, remove from service and return to CECO for inspection, engine fuel pump at intervals not to exceed 600 hours TIS since the last inspection in accordance with the Accomplishment Instructions of AlliedSignal SB LT 101-73-20-0203, dated August 18, 1999, or Honeywell International Inc. SB LT 101-73-20-0203, Revision 1, dated January 5, 2001.

(f) Engine fuel pumps that exhibit wear beyond the limits specified in AlliedSignal SB LT 101-73-20-0203, dated August 18, 1999, or Honeywell International Inc. SB LT 101-73-20-0203, Revision 1, dated January 5, 2001, may not be returned to service.

(g) For the purposes of this AD, a serviceable part is defined as a new part, or a part that has been inspected by CECO in accordance with AlliedSignal SB LT 101-73-20-0203, dated August 18, 1999, or Honeywell International Inc. SB LT 101-73-20-0203, Revision 1, dated January 5, 2001, and that has not accumulated 600 hours TIS since new, or since inspection by CECO.

(h) 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, Los Angeles Aircraft Certification Office (LAACO). Operators must submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, LAACO.

Note 2:

Information concerning the existence of approved alternative methods of compliance with this airworthiness directive, if any, may be obtained from the LAACO. 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, LAACO. The request should be forwarded through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, LAACO.

(i) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the aircraft to a location where the requirements of this AD can be accomplished.

(j) The inspection shall be done in accordance with the following AlliedSignal and Honeywell International Inc. service bulletins:

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.
