Question? Question? What do all these What do all these regulations have in regulations have in common? common?

Answer Answer They set: Airworthiness Airworthiness Standards ! Standards !

THESE FAR SET THESE FAR SET PART-39 PART-43 PERFORMANCE PART-91 PART-121 STANDARDS PART-135PART-145

Two Standards Two Standards v Airworthiness Standard and and v Performance Standard

Why TWO STANDARDS ?

BECAUSE FOR AN AIRCRAFT TO BE “AIRWORTHY” IT MUST MEET TWO STANDARDS

DEFINITION OF “AIRWORTHY” DEFINITION OF “AIRWORTHY” v Airworthy is when the aircraft meets its type design and is in a condition for safe operation. (Ref: Act of 58 and the Standard A/W certificate) (Ref: Act of 58 and the Standard A/W certificate)

AIRWORTHY AIRWORTHY v TYPE DESIGN = AIRWORTHINESS STANDARD v CONDITION FOR SAFE OPERATION = PERFORMANCE STANDARD

INTERIM SUMMARY INTERIM SUMMARY u Federal Aviation Act of 1958 u Airworthiness Standards (FAR 21, 23, 25, 27, 29, 31, 33, 35, 36, 39, SFAR and S.R..) u Performance Standards: (FAR 39, 43, 91, 121, 135, (FAR 39, 43, 91, 121, 135, and 145.) and 145.)

INTERIM SUMMARY INTERIM SUMMARY v DEFINITION OF AIRWORTHY v “TWO STANDARDS,” A MAJOR ALTERATION OR REPAIR MUST MEET THE A/C TYPE CERTIFICATION RULES AND MEET THE PERFORMANCE RULES IN PART 43.

DEFINITIONSDEFINITIONS

Field Approvals

DEFINITION: DEFINITION: Field Approval: is the granting of FAA approval, by an FAA A/W Inspector, (FSDO) by examining data, or by physical inspection or testing, or approving multiple testing, or approving multiple installations by the same modifier installations by the same modifier

Field Approval Facts Field Approval Facts –Not found in the FARs –Policy only –FAA Airworthiness Inspector sign Block 3 of FAA Form 337 Inspector sign Block 3 of FAA Form 337

Field Approval Facts Field Approval Facts There are only 3 kinds of field approvals: 1. Examination of Data only! “Approves” acceptable data for “Approves” acceptable data for major repairs/major alterations major repairs/major alterations

FIELD APPROVAL FACTS FIELD APPROVAL FACTS 2. Physical inspection, demonstration, or testing of the repair or alteration.

FIELD APPROVAL FACTS FIELD APPROVAL FACTS 3. Examination of Data only for duplication on identical make and model by the original modifier.

Notice Notice You are not entitled to a Field Approval even if the Form 337 is “perfect.”

Why Not? Why Not? 1. Field Approvals are policy only and are not regulatory. 2. Authority to grant a field approval res ts on the FAA approval res ts on the FAA A/W Inspector alone ! A/W Inspector alone !

Suggestion Suggestion If your field approval request has been denied try another inspector. If it is denied twice--check your paper work.

You have one of three Kinds of Field Approvals You have one of three Kinds of Field Approvals 1.Data approval 2.Approval by physical inspection or testing 3.Data approval for multiple repairs or alterations

DON’T FORGET, YOU GET TO SHARE THE BLAME DON’T FORGET, YOU GET TO SHARE THE BLAME The Form 337 still needs the conformity statement signed and the approval for return to service block checked, as well as the aircraft’s maintenance records completed.

A completed Form goes to the owner/operator 1 - to the FAA within 48 hours A fuel tank in the baggage or Cabin 1 - goes to the owner/operator 1 - to the FAA written 48 hours 1 - stays in the cockpit/cabin
