Airworthiness Directive · Amendment 39-16494 · Fuel
EADS CASA (Type Certificate Previously Held by Construcciones Aeronauticas, S.A.) Model CN-235, CN-235-100, CN-235-200, and CN-235-300 Airplanes, and Model C-295 Airplanes
This AD applies to EADS CASA (Type Certificate previously held by Construcciones Aeronauticas, S.A.) Model CN-235, CN-235-100, CN-235-200, and CN-235-300 airplanes, and Model C-295 airplanes, all serial numbers; certificated in any category.
We are superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Do the following actions.
(1) Within 6 months after June 5, 2008 (the effective date of AD 2008-09-22), do the revisions specified in (g)(1)(i) or (g)(1)(ii) of this AD.
(i) Revise the Airworthiness Limitations section of the Instructions for Continued Airworthiness to include the CDCCL data using a method approved in accordance with the procedures specified in paragraph (i)(1) of this AD.
(ii) Revise the Airworthiness Limitations section of the Instructions for Continued Airworthiness by incorporating the information in EADS CASA CN-235/C-295 Technical Document DT-0-C00-05001, Issue C, dated October 2006. Where this EADS CASA technical document refers to an EADS CASA component maintenance manual (CMM), use the applicable CMM specified in Table 1 of this AD.

Note 1: Table 1 of this AD does not include CMMs 28-22-15, CE 400150-E01, and C 17MQ0020-005SE, which are listed in EADS CASA CN-235/C-295 Technical Document DT-0-C00-05001, Issue C, dated October 2006. These CMM document numbers no longer apply. In addition, CMM document number 28-21-81 in EADS CASA CN-235/C-295 Technical Document DT-0-C00-05001, Issue C, dated October 2006, should be CMM document number 28-20-81.
(2) After accomplishing the actions specified in paragraph (g)(1) of this AD, no alternative CDCCLs may be used unless the CDCCLs are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (i)(1) of this AD.
Do the following actions.
(1) Within 3 months after the effective date of this AD, revise the Airworthiness Limitations section of the Instructions for Continued Airworthiness by incorporating the information in EADS CASA CN-235/C-295 Technical Document DT-0-C00-05001, Issue D, dated October 2008. Where this EADS CASA technical document refers to an EADS CASA CMM, use the applicable CMM specified in Table 1 of this AD. Doing this revision terminates the requirements specified in paragraph (g) of this AD.
Note 2: Notwithstanding any other maintenance or operational requirements, components that have been identified as airworthy or installed on the affected airplanes before the revision of the fuel airworthiness limitations, as required by paragraphs (g) and (h) of this AD, do not need to be reworked in accordance with the CDCCLs. However, once the fuel airworthiness limitations have been revised, future maintenance actions on these components must be done in accordance with the CDCCLs.
(2) After accomplishing the actions specified in paragraph (h)(1) of this AD, no alternative CDCCLs may be used unless the CDCCLs are approved as an AMOC in accordance with the procedures specified in paragraph (i)(1) of this AD.
(3) Within 6 months after the effective date of this AD, accomplish the modifications specified in paragraphs (h)(3)(i), (h)(3)(ii), and (h)(3)(iii) of this AD, as applicable.
(i) For Model CN-235, CN-235-200, and CN-235-300 airplanes having serial numbers identified in EADS CASA Service Bulletin SB-235-21-18, dated August 2, 2007: Add thermal insulation to the air condition compression system, in accordance with the Accomplishment Instructions of EADS CASA Service Bulletin SB-235-21-18, dated August 2, 2007.
(ii) For Model CN-235, CN-235-200, and CN-235-300 airplanes having serial numbers identified in EADS CASA Service Bulletin SB-235-28-18, dated August 2, 2007: Apply double bonding connections on fuel tubes and do general visual inspections for damage inside of the tank, in accordance with the Accomplishment Instructions of EADS CASA Service Bulletin SB-235-28-18, dated August 2, 2007. If any damage is found inside the tank, before further flight, contact EADS CASA for repair instructions and do the repair.
(iii) For Model CN-235, CN-235-200, and CN-235-300 airplanes having serial numbers identified in EADS CASA Service Bulletin SB-235-24-20, dated August 2, 2007: Modify the separation between the center wing electrical harnesses and fuel tubes, in accordance with the Accomplishment Instructions of EADS CASA Service Bulletin SB-235-24-20, dated August 2, 2007.
Note 3: This AD differs from the MCAI and/or service information as follows: (1) The European Aviation Safety Agency (EASA) AD 2009-0146, dated July 3, 2009, inadvertently refers to the incorrect service bulletins. For applying double bonding connections on fuel tubes and doing general visual inspections for damage inside the tank, we refer to EADS CASA Service Bulletin SB-235-28-18, dated August 2, 2007. For modifying the separation between the center wing electrical harnesses and fuel tubes, we refer to EADS CASA Service Bulletin SB-235-24-20, dated August 2, 2007. (2) The EASA AD 2009-0146, dated July 3, 2009; and EADS CASA Service Bulletin SB-235-28-18, dated August 2, 2007; do not specify corrective actions if any damage is found inside the tank. If any damage is found inside the tank, this AD requires contacting EADS CASA for repair instructions and doing the repair.
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.
