Airworthiness Directive · Amendment 39-14199 · The New Piper Aircraft, Inc. Models PA-34-200T, PA-34-220T, PA-44-180, and PA-44-180T Airplanes
The New Piper Aircraft, Inc. Models PA-34-200T, PA-34-220T, PA-44-180, and PA-44-180T Airplanes
This AD applies to the following airplane models and serial numbers that are certificated in any category, equipped with a model 91E92-1 or model 91E93-1 aircraft heater fuel pump:
(1) Group 1: The New Piper Aircraft, Inc. airplanes retained from AD 2003-11-14:
| Model | Serial Nos. |
|---|---|
| PA-34-200T | 34-7570002 through 34-8170092. |
| PA-34-220T | 34-8133002 through 3449278. |
| PA-44-180 | 44-7995001 through 4496168. |
| PA-44-180T | 44-8107001 through 44-8207020. |
(2) Group 2: The New Piper Aircraft, Inc. airplanes (not included in AD 2003-11-14) added to the applicability of this AD:
| Model | Serial Nos. |
|---|---|
| PA-34-220T | 3449279 through 3449309. |
| PA-44-180 | 4496169 through 4496190. |
What Is the Unsafe Condition Presented in This AD?
(d) This AD is the result of an investigation that concluded that after issuance of AD 2003-11-14, additional fuel pumps that did not meet the quality control (inspection or design) requirements of the AD were installed in Models PA-34-220T and PA-44-180 airplanes. We are issuing this AD to correct quality control problems with the heater fuel pump, which could result in failure of the heater fuel pump. Such failure could lead to fire or explosion in the cockpit.
The FAA adopts an airworthiness directive (AD) to supersede AD 2003-11-14, which applies to certain The New Piper Aircraft, Inc. (Piper) Models PA-34-200T, PA-34-220T, PA-44-180, and PA-44-180T airplanes that have a model 91E92-1 or model 91E93-1 combustion heater fuel pump installed. AD 2003-11-14 currently requires you to do a one- time inspection of the combustion heater fuel pumps for fuel leakage. If leakage is found, repair or replace the fuel pump. This AD retains all the actions of AD 2003-11-14 and includes additional serial numbers for the Models PA-34-220T and PA-44-180 airplanes in the applicability section. This AD results from an investigation that concluded that after the issuance of AD 2003-11-14, additional fuel pumps that did not meet the quality control (inspection or design) requirements of the AD had been installed in Models PA-34-220T and PA-44-180 airplanes. We are issuing this AD to correct quality control problems with the heater fuel pump, which could result in failure of the heater fuel pump. Such failure could lead to fire or explosion in the cockpit.
What actions must I do to address this problem for Group 1 airplanes? To address this problem for Group 1 airplanes, you must do the following:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Visually inspect any installed aircraft heater fuel pump (model 91E92-1 or model 91E93-1 for leakage | Within the next 10 hours time-in-service (TIS), after June 20, 2003 (the effective date of AD 2003-11-14), unless already done | Follow The New Piper Aircraft, Inc.
