We are adopting a new airworthiness directive (AD) for certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42 and ATR72 airplanes. This AD was prompted by reports of fuel quantity indication malfunctions caused by fuel probe failure. This AD requires identifying the part number and serial number of the fuel probes, and replacing the fuel probes if necessary. We are issuing this AD to prevent fuel probe failure, which could lead to undetected fuel starvation and consequent dual engine in-flight flame-out.
Within 5,000 flight hours or 24 months, whichever occurs first after the effective date of this AD: Inspect to determine if any fuel probe has any part number and serial number identified in table 1 to paragraph (g) of this AD. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number and serial number of the part can be conclusively determined from that review.
| Airplane model | Part No. | Serial No. |
|---|---|---|
| ATR 42 | 766-046-2 | 1046 through 1083 inclusive. |
| ATR 42 | 766-047-2 | 1154 through 1214 inclusive. |
| ATR 42 | 766-048-2 | 1150 through 1197 inclusive. |
| ATR 42 | 768-055 | 1156 through 1227 inclusive. |
| ATR 42 | 798-038 | 1150 through 1238 inclusive. |
| ATR 72 | 766-793-1 | 1469 through 1826 inclusive. |
| ATR 72 | 766-795-2 | 1661 through 2093 inclusive. |
| ATR 72 | 766-796-2 | 1722 through 2152 inclusive. |
| ATR 72 | 766-797-2 | 1663 through 2051 inclusive. |
| ATR 72 | 766-983-1 | 2200 through 2652 inclusive. |
| ATR 72 | 768-100 | 1511 through 1876 inclusive. |
If any fuel probe is found that has any part number and serial number specified in table 1 to paragraph (g) of this AD: Within 5,000 flight hours or 24 months, whichever occurs first after the effective date of this AD, replace the fuel probe with a serviceable fuel probe, using a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (EASA); or ATR-GIE Avions de Transport Régional's EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.
Note 1 to paragraph (h) of this AD: Guidance on accomplishing the replacement can be found in Job Instruction Card 28-42-72, RAI 10000-001, “Removal and Installation of Fuel Quantity or Fuel Temp/Quantity Probe” of the ATR-42 Aircraft Maintenance Manual; and Job Instruction Card 28-42-72, RAI 10000-002, “Removal and Installation of Fuel Quantity or Fuel Temp/Quantity Probe” of the ATR-72 Aircraft Maintenance Manual.
For the purposes of this AD, a fuel probe is serviceable if it meets the criterion specified in paragraph (i)(1) or (i)(2) of this AD.
(1) The fuel probe is not listed in table 1 to paragraph (g) of this AD.
(2) The fuel probe is listed in table 1 to paragraph (g) of this AD, but has control tag “C” marked on the part identification plate, as specified in Zodiac Aerospace Service Bulletin 766983-28-002, Revision 1, dated March 24, 2014.
As of the effective date of this AD, no person may install, on any airplane, a fuel probe having any part number and serial number identified in table 1 to paragraph (g) of this AD, unless control tag “C” is marked on the part identification plate, as specified in Zodiac Aerospace Service Bulletin 766983-28-002, Revision 1, dated March 24, 2014.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
