2009-09-04 EADS-PZL "Warszawa-Okecie'' S.A.: Amendment 39- 15890; Docket No. FAA-2009-0371; Directorate Identifier 2009-CE-021- AD. Effective Date (a) This airworthiness directive (AD) becomes effective May 18, 2009. Affected ADs (b) None. Applicability (c) This AD applies to Model PZL-104 WILGA 80 airplanes, all serial numbers, certificated in any category. Subject (d) Air Transport Association of America (ATA) Code 53: Fuselage. Reason (e) The mandatory continuing airworthiness information (MCAI) states: An inspection of a PZL-104 aeroplane that had a relatively long operational background revealed a severe corrosion of the steel front fuselage structural elements. It is likely that such corrosion can also be present on other aeroplanes of similar design and operational history. If left uncorrected, this condition could lead to loss of strength of the structural front posts elements and consequent reduction of the structural strength of the aeroplane. For the reason stated above, this Airworthiness Directive (AD) mandates inspecting the fuselage front posts, repairing any corrosion found and replacing pads made of foam rubber by pads made of Neoprene to prevent water ingression. Actions and Compliance (f) Unless already done, do the following actions. (1) Within 12 years from date of manufacture or within the next two months after May 18, 2009 (the effective date of this AD), whichever occurs later, inspect the fuselage front posts for signs of corrosion following paragraph 6.A. of EADS-PZL "Warszawa- Okecie'' S.A. Mandatory Bulletin No. 10409036, dated March 18, 2009. (2) If corrosion or any corrosion damage is found during the inspection required in paragraph (f)(1) of this AD, before further flight, repair or replace any parts where corrosion or corrosion damage was found in accordance with an FAA-approved repair solution obtained from EADS-PZL "Warszawa-Okecie'' S.A. (3) Within 12 years from date of manufacture or within the next two months after May 18, 2009 (the effective date of this AD), whichever occurs later, replace the rear glass padding following paragraph 6.C. of EADS-PZL "Warszawa-Okecie'' S.A. Mandatory Bulletin No. 10409036, dated March 18, 2009. FAA AD Differences Note: This AD differs from the MCAI and/or service information as follows: (1) The MCAI specifies revising the airplane maintenance program to include a repetitive inspection of the fuselage front posts. We are not including the maintenance program revision action in this AD. The Administrative Procedure Act does not permit the FAA to "bootstrap'' a long-term requirement into an urgent safety of flight action where the rule becomes effective at the same time the public has the opportunity to comment. The short-term action and the long-term action are analyzed separately for justification to bypass prior public notice. (2) After issuing this AD, we may initiate further AD action (notice of proposed rulemaking followed by a final rule) to require a maintenance program revision action to do a repetitive inspection of the fuselage front posts. Credit will be given in any subsequent action for the inspection done under this AD. Other FAA AD Provisions (g) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to Attn: Doug Rudolph, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4059; fax: (816) 329-4090. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.
