96-07-14 CONSTRUCCIONES AERONAUTICAS, S.A. (CASA): Amendment 39-9564. Docket 92-NM-75-AD.
Applicability: All Model C-212-CB, -CC, -CD, -CE, and -CF series airplanes, certificated in any category.

NOTE 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been otherwise modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (e) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

Compliance: Required as indicated, unless accomplished previously.

To prevent reduced structural integrity of the airplane, accomplish the following:

(a) For Model C-212-CB series airplanes: Prior to the accumulation of 16,500 total landings, or within 6 months after the effective date of this AD, whichever occurs later, replace the horizontal stabilizer-to-fuselage attach fittings, part numbers 212-31101.05 and 212-31102.05, with part numbers 212-31122.03 and 212-31123.05, respectively, in accordance with the CASA C-212 Aircraft Maintenance Manual, Chapter 5, Section 5-20, task number 55.15.

NOTE 2: Replacement of the attach fittings on Model C-212-CB series airplanes may be accomplished by replacing part numbers 212-31101.05 and 212-31102.05 with part numbers 212- 31123.30 and 212-31122.29, respectively.

(b) For all airplanes: Incorporate a revision into the FAA-approved maintenance inspection program that provides for inspection of the Principal Structural Elements (PSE) defined in CASA SupplementalInspection Document (SID) C-212-PV-01-SID, dated June 1, 1987 (hereinafter referred to as the "Document"), at the later of the times specified in paragraphs (b)(1) and (b)(2) of this AD.

NOTE 3: Certain thresholds and intervals for inspections of the wing flap control system required by AD 89-02-08 R1, amendment 39-6280, are more restrictive than those specified in the Document. Where differences exist, the thresholds and intervals specified in AD 89-02-08 R1 prevail.

(1) Prior to the accumulation of 20,000 total landings or 20,000 total hours time-in- service, whichever occurs first. Or

(2) Within 9 months after the effective date of this AD.

(c) Any cracked structure detected during the inspections required by paragraph (b) of this AD must be repaired or replaced, prior to further flight, in accordance with the instructions in the Document, or in accordance with other data meeting the certification basis of the airplane that is approved by the FAA or by theDirecci n General de Aviaci n Civil (DGAC).

(d) Within 10 days after accomplishing each inspection required by paragraph (b) of this AD, report the results (positive or negative) of each inspection required by paragraph (b) of this AD to CASA in accordance with the Document. Information collection requirements contained in this regulation have been approved by the Office of Management and Budget (OMB) under the provisions of the Paperwork Reduction Act of 1980 (44 U.S.C. 3501 et seq.) and have been assigned OMB Control Number 2120-0056.

(e) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Standardization Branch, ANM- 113, FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Standardization Branch, ANM-113.

NOTE 4: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Standardization Branch, ANM-113.

(f) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of this AD can be accomplished.

(g) The maintenance program revision shall be done in accordance with CASA Supplemental Inspection Document (SID) C-212-PV-01-SID, dated June 1, 1987. (NOTE: The date of Volumes 2 and 3 of the SID is indicated only on the title page of the volume.) This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.
