S'agissant d'un avion de plus de 5,7 tonnes de MTOW, il n'est pas proposé de traduction de l'AD jointe.
Nota pour les exploitants et organismes d'entretien d'aéronefs inscrits au registre français :
Si l'AD jointe invite à un contact vers l'autorité primaire de l'AD, contacter le bureau concerné du département
certification-produits de l'EASA.
Si pour l'exécution d'une tâche donnée, l'AD jointe se réfère à une qualification de personnel répondant à une
réglementation nationale, il est possible de faire intervenir, pour cette tâche, du personnel de qualification
équivalente acceptée dans l'Union Européenne.
Si l'AD jointe se réfère à une donnée de navigabilité ou une instruction pour le maintien de la navigabilité (Manuel
de Vol, Manuel de Maintenance, ...) qui n'est pas celle approuvée ou pas celle en vigueur en France ou si l'AD
jointe présente une difficulté d'application liée à sa spécificité nationale, exposer le problème auprès du
département technique du GSAC (par courriel à "[email protected]" ou par fax au 01 46 90 48 48) ou auprès du
bureau concerné du département certification-produits de l'EASA.

EASA
AIRWORTHINESS DIRECTIVE
AD No: 2007-0007
Date: 09 January 2007
No person may operate an aircraft to which an Airworthiness Directive applies, except in accordance with the
requirements of that Airworthiness Directive unless otherwise agreed with the Authority of the State of Registry.
Type Approval Holder’s Name:
Type/Model designation(s):
EADS CASA
CN-235 series, C-295
TCDS Number : DGAC España Nr. 01-86/14
Foreign AD : Not applicable.
Supersedure : Not applicable.
ATA 28
Fuel - Fuel Tank Safety ALS Part 5 - Fuel Airworthiness Limitations
(FAL) Implementation
Manufacturer(s):
EADS CASA; Construcciones Aeronauticas, S.A. (CASA).
Applicability:
All Model CN-235, CN-235-100, CN-235-200, CN-235-300 and C-295 aircraft, all
serial numbers
Reason:
Subsequent to accidents involving Fuel Tank System explosions in flight (Boeing
747-131 flight TWA800) and on ground, the FAA published Special Federal
Aviation Regulation 88 (SFAR88) in June 2001. SFAR 88 required a safety review
of the aircraft Fuel Tank System to determine that the design meets the
requirements of FAR § 25.901 and § 25.981(a) and (b).
A similar regulation has been recommended by the JAA to the European National
Aviation Authorities in JAA letter 04/00/02/07/03-L024 of 3 February 2003. The
review was requested to be mandated by NAA’s using JAR § 25.901(c), § 25.1309.
In August 2005 EASA published a policy statement on the process for
developing instructions for maintenance and inspection of Fuel Tank System
ignition source prevention (EASA D 2005/CPRO,
www.easa.eu.int/home/cert_policy_statements_en.html ) that also included the
EASA expectations with regard to compliance times of the corrective actions on
the unsafe and the not unsafe part of the harmonised design review results. On a
global scale the TC holders committed themselves to the EASA published
compliance dates (see EASA policy statement). The EASA policy statement was
revised in March 2006: the date of 31-12-2005 for the unsafe related actions was
set at 01-07-2006.
Fuel Airworthiness Limitations are items arising from a systems safety analysis
that have been shown to have failure mode(s) associated with an ‘unsafe
condition’ as defined in FAA’s memo 2003-112-15 ‘SFAR 88 – Mandatory Action
Decision Criteria’. These are identified in Failure Conditions for which an
unacceptable probability of ignition risk could exist if specific tasks and/or practices
are not performed in accordance with the manufacturers’ requirements.

This EASA Airworthiness Directive mandates the Fuel Airworthiness Limitations
(comprising maintenance /inspection tasks and Critical Design Configuration Control
Limitations (CDCCL)) for the type of aircraft, that resulted from the design reviews
and the JAA recommendation and EASA policy statement mentioned above.
Effective Date:
23 January 2007
Compliance:
Unless previously accomplished, compliance is required as follows:
1. Fuel Airworthiness Limitations
Within 3 months after the effective date of this directive, amend the aircraft
maintenance program to incorporate the Fuel Airworthiness Limitation
maintenance & inspection tasks as defined in EADS CASA document
DT-0-C00-05001 at Issue C or later approved revision.
2. Critical Design Configuration Control Limitations (CDCCL)
Before 01 July 2007:
-
Amend the operator’s internal documentation to reflect the data contained in
EADS CASA Fuel Airworthiness Limitations document DT-0-C00-05001 issue
C and provide appropriate text to highlight the existence of each CDCCL
revision; and
-
Amend the operator’s internal procedures and documentation ensuring
management of control of CDCCL and revisions thereof.
Note: No retroactive action on aircraft is required, other than the above mentioned
amendment of the documentation.
