Models named: A109E. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

Model A109E helicopters, up to and including serial numbers 11057, excluding serial numbers 11001, 11005, 11047, 11049, 11055 and 11056, with engine exhaust ejectors, part number 109-0601-51, installed, certificated in any category. Note 1: This AD applies to each helicopter identified in the preceding applicability provision, regardless of whether it has been otherwise modified, altered, or repaired in the area subject to the requirements of this AD. For helicopters 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 (f) 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.

Compliance

Required as indicated, unless accomplished previously. To prevent loss of the metallic clamp or the engine exhaust ejector, damage to the main or tail rotor system, and subsequent loss of control of the helicopter, accomplish the following: (a) Prior to further flight, in accordance with Part I of the Compliance Instructions in Agusta Bollettino Tecnico No. 109EP-3, dated December 22, 1998 (Technical Bulletin), inspect the exhaust ejector to ejector saddle locking system, the dampers at the bottom of the ejector saddle, and the torque of the metallic clamp, and install safety wire on the metallic clamp. If any damage is found as a result of the inspection, accomplish Part II of the Compliance Instructions in the Technical Bulletin prior to further flight. (b) Within the next 10 hours time-in-service (TIS), inspect the dampers and metallic clamps, and reposition and modify the ejector saddle and the locking metallic clamp in accordance with Part II of the Compliance Instructions in the Technical Bulletin. (c) Thereafter, at intervals not to exceed 25 hours TIS, inspect the metallic clamp, locking mechanism, and dampers in accordance with Part III of the Compliance Instructions in the Technical Bulletin. (d) Before further flight after December 31, 2000, modify the engine exhaust ejectors, part number (P/N) 109-0601-51, by installing a kit, P/N 109-0822-94, in accordance with the Compliance Instructions in Agusta Technical Bulletin No. 109EP-5, dated December 22, 1999. (e) Installing a kit, P/N 109-0822-94, is terminating action for the requirements of this AD. (f) 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, Regulations Group, Rotorcraft Directorate, FAA. Operators shall submit their requests through a FAA Principal Maintenance Inspector, who may concur or comment and then send it to the Manager, Regulations Group. Note 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Regulations Group. (g) Special flight permits may be issued in accordance with §§ 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the helicopter to a location where the requirements of this AD can be accomplished. (h) The inspections shall be done in accordance with Parts I, II, and III of the Compliance Instructions in Agusta Bollettino Tecnico No. 109EP-3, dated December 22, 1998. The incorporation by reference of that document was approved previously by the Director of the Federal Register, in accordance with 5 U.S.C. 552(a) and 1 CFR part 51, as of April 5, 1999 (64 FR 13502, March 19, 1999).
