EADS CASA (Type Certificate Previously Held by Construcciones Aeronauticas, S.A.) Airplanes
Superseded. A later AD replaced this one: AD 2016-26-03. Comply with the one in force.
This AD applies to EADS CASA (Type Certificate previously held by Construcciones Aeronauticas, S.A.) Model CN-235, CN-235-100, CN-235-200, CN-235-300, and C-295 airplanes, certificated in any category, all manufacturer serial numbers.
We are adopting a new airworthiness directive (AD) for all EADS CASA (Type Certificate previously held by Construcciones Aeronauticas, S.A.) Model CN-235, CN-235-100, CN-235-200, CN-235-300, and C-295 airplanes. This AD requires inspection of the feeder cables of certain fuel booster pumps for damage (including, but not limited to, signs of electrical arcing and fuel leaks), and replacement if necessary. This AD was prompted by a report of an in-flight problem with the fuel transfer system. We are issuing this AD to detect and correct damage to certain fuel booster pumps, which could create an ignition source in the fuel tank vapor space, and result in a fuel tank explosion and consequent loss of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within the times specified in paragraph (g)(1) or (g)(2) of this AD, as applicable: Perform a detailed visual inspection for damage (including, but not limited to, signs of electrical arcing and fuel leaks) of the electrical feeder cables of each fuel booster pump having part number (P/N) 1C12-34 or 1C12-46, in accordance with the instructions of Airbus Military All Operator Letter 235-025, dated July 29, 2013 (for Model CN-235 airplanes); or Airbus Military All Operator Letter 295-025, Revision 01, dated August 1, 2013 (for Model C-295 airplanes).
(1) For each fuel booster pump that has not been replaced as of the effective date of this AD: Prior to the accumulation of 300 total flight hours or within 5 cycles after the effective date of this AD, whichever occurs later.
(2) For each fuel booster pump that has been replaced as of the effective date of this AD: Within 300 flight hours since the most recent fuel booster pump replacement, or within 5 flight cycles after the effective date of this AD, whichever occurs later.
If any damage (including, but not limited to, signs of electrical arcing and fuel leaks) is found during the inspection required by paragraph (g) of this AD: Within the time specified in paragraph (h)(1) or (h)(2) of this AD, replace the affected fuel booster pump with a serviceable pump, in accordance with Airbus Military All Operator Letter 235-025, dated July 29, 2013 (for Model CN-235 airplanes); or Airbus Military All Operator Letter 295-025, Revision 01, dated August 1, 2013 (for Model C-295 airplanes).
(1) Before further flight.
(2) Within 10 days following the inspection, provided that the airplane is operated under the conditions specified in Airbus Military All Operator Letter 235-025, dated July 29, 2013 (for Model CN-235 airplanes); or Airbus Military All Operator Letter 295-025, Revision 01, dated August 1, 2013 (for Model C-295 airplanes).
At the applicable time specified in paragraph (i)(1) or (i)(2) of this AD, submit an inspection report to EADS CASA (Airbus Military), in accordance with Airbus Military All Operator Letter 235-025, dated July 29, 2013 (for Model CN-235 airplanes); or Airbus Military All Operator Letter 295-025, Revision 01, dated August 1, 2013 (for Model C-295 airplanes).
(1) If the inspection was done on or after the effective date of this AD: Submit the report within 10 days after the inspection.
(2) If the inspection was done before the effective date of this AD: Submit the report within 10 days after the effective date of this AD.
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.
