Show the answer and explanation

Correct answer: C. In block 8 of FAA Form 337

  • A — incorrect Block 3 is used for the FAA field approval signature when no existing approved data is available; the reference to the AC data belongs in the description of work in block 8.
  • B — incorrect A major alteration must be documented on FAA Form 337, and the AC reference is required on that form, not merely in the maintenance records.
  • C — correct The AC states its alteration data may be used as approved data for major alterations when the AC chapter, page, and paragraph are listed in block 8 of FAA Form 337 and the data is appropriate, directly applicable, and not contrary to manufacturer's data.

BACKGROUND

AC 43.13-2B, Acceptable Methods, Techniques, and Practices - Aircraft Alterations, contains methods acceptable to the Administrator for the inspection and alteration of non-pressurized areas of civil aircraft of 12,500 pounds gross weight or less. The excerpt in FAA-H-8083-30B chapter 2 explains that this data generally pertains to minor alterations, but it may be used as approved data for major alterations when the AC chapter, page, and paragraph are listed in block 8 of FAA Form 337 and the user has determined the data is appropriate to the product being altered, directly applicable to the alteration being made, and not contrary to the manufacturer's data. Block 8, on the reverse of the form, is the description of the work accomplished and must reference the approved data used.

STUDY TIP

Know the three conditions (appropriate, directly applicable, not contrary to manufacturer's data) and that the citation goes in block 8, the description of work.

KEY POINTS

  • AC 43.13-2B generally provides acceptable data for minor alterations.
  • It can serve as approved data for a major alteration if cited by chapter, page, and paragraph in block 8 of FAA Form 337.
  • The data must be appropriate, directly applicable, and not contrary to manufacturer's data.
