Airworthiness Directive · Amendment 39-14153 · The New Piper Aircraft, Inc. PA-34 Series Airplanes
The New Piper Aircraft, Inc. PA-34 Series Airplanes
This AD affects Models PA-34-200, PA-34-200T, and PA-34-220T airplanes, all serial numbers, that are certificated in any category.
The FAA adopts an airworthiness directive to supersede AD 93- 24-14 applicable to all The New Piper Aircraft, Inc. (Piper) PA-34 series airplanes. This AD results from many service difficulty reports related to the collapse of the nose landing gear (NLG). Consequently, this AD retains the actions required in AD 93-24-14, requires you to inspect the NLG and components of the NLG using new procedures for rigging the nose gear installation, and requires you to replace unserviceable parts. We are issuing this AD to detect, correct, and prevent failure in certain components of the NLG, lack of cleanliness of the NLG due to inadequate maintenance, or lack of lubricant in the NLG or NLG components. This failure of the NLG could lead to loss of control of the airplane during take-off, landing, or taxiing operations.
To address this problem, you must do the following:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Replace the bolt and stack up that connects the upper drag link to the nose gear trunnion with new parts (or FAA-approved equivalent part numbers (P/N)) of the following: (i) Piper P/N 400 274 (AN7-35) bolt; (ii) Piper P/N 407 591 (AN960-716L) washer, as applicable; (iii) Piper P/N 407 568 (AN960-716); (iv) Piper P/N 404 396 (AN320-7) nut; and (v) Piper P/N 424 085 cotter pin. | Within the next 100 hours time-in-service (TIS) after January 28, 1994 (the effective date of AD 93-24-14), unless already done within the last 400 hours TIS before January 28, 1994 (compliance with AD 93-24-14). Repetitively replace thereafter at intervals not to exceed 500 hours TIS. Continue to repetitively replace until the actions in paragraphs (e)(2) and (e)(3) of this AD begin | Follow Figure 1 of this AD. |
