AD 2002-21-51 Airworthiness Directives; Eurocopter France Model AS355E, F, F1, F2, and N Helicopters
Models named: AS355E, F, F1, F2, N. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
Model AS355E, F, F1, F2, and N helicopters, with a main gearbox (MGB) lubrication pump (pump), part number 355A32-0700-00, -01, -01M, 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 (c) 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 failure of the MGB pump, seizure of the MGB, loss of drive to an engine and main rotor, and subsequent loss of control of the helicopter, accomplish the following: (a) Before the first flight of each day and at intervals not to exceed 10 hours time-in-service (TIS), check the MGB magnetic chip detector plug (chip detector) for any metal particles. Also, check for dark oil in the MGB oil-sight glass. An owner/operator (pilot) holding at least a private pilot certificate may perform this visual check and must enter compliance into the aircraft maintenance records in accordance with 14 CFR 43.11 and 91.417(a)(2)(v). Note 2: Eurocopter France Alert Telex No. 05.00.40, dated June 6, 2002, pertains to the subject of this AD. (1) Before further flight, if any metal particles are found on the chip detector, inspect the pump. (2) Before further flight, if dark oil is observed through the MGB oil-sight glass, take an oil sample to confirm that the oil is dark or dark purple. If the oil sample is dark or dark purple, before further flight, inspect the pump. (3) While inspecting the pump, if you find any of the following, replace the MGB and the pump with an airworthy MGB and pump before further flight: (i) Crank pin play, (ii) Out of round bronze bushing (A of Figure 1), (iii) Offset of the driven gear pinion, (iv) Metal chips, or (v) Wear (C of Figure 1). See the following Figure 1: BILLING CODE 4910-13-P ER18DE02.003 BILLING CODE 4910-13-C Note 3: If wear occurs in B only in Figure 1, replacing the MGB and the pump is not necessary. (b) Before installing a different MGB or a pump with any TIS, accomplish the requirements of paragraph (a) of this AD. (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, Regulations Group, Rotorcraft Directorate, FAA. Operators shall submit their requests through an FAA Principal Maintenance Inspector, who may concur or comment and then send it to the Manager, Regulations Group. Note 4: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Regulations Group. (d) Special flight permits may be issued in accordance with 14 CFR 21.197 and 21.199 to operate the helicopter to a location where the requirements of this AD can be accomplished. (e) This amendment becomes effective on January 2, 2003, to all persons except those persons to whom it was made immediately effective by Emergency AD 2000-21-51, issued October 17, 2002, which contained the requirements of this amendment. Note 5: The subject of this AD is addressed in Direction Generale De L'Aviation Civile, France, AD No. 2002-331-071(A), dated July 10, 2002. Issued in Fort Worth, Texas, on December 10, 2002.
