g.   Item 7 - Approval for Return to Service.    FAR Part 43 establishes
the conditions under which major repairs or alterations to airframes,
powerplants, propellers, and/or appliances may be approved for return to service.  This portion of the form is used to indicate approval or rejection of the repair or alteration of the unit involved and to identify the person or agency making the airworthiness inspection.  Check the "approved" or "rejected" box to indicate the finding.  Additionally, check the appropriate box to indicate who made the finding.  Use the box labeled "other" to indicate a finding by a person other than those listed.  Enter the date the finding was made.  The authorized person who made the finding should sign the form and enter the appropriate certificate or
designation number.
Note - A signature in item 7, "Approval for Return to Service," does not signify FAA approval unless the box to the left of "FAA Flight Standards Inspector" or "FAA Designee" is checked.  The other person.-, listed in item 7, are authorized to "approve for return to service" if the repair or alteration is accomplished using FAA-approved data, is performed in accordance with applicable FAR, and found to conform.

This slide more closely resembles the back of a 337.

(2)	Data used as a basis for approving major repairs or alterations for return to service must be FAA-approved prior to its use for that purpose and includes: FAR (e.g., airworthiness directives), AC's (e.g., AC 43.13-lA under certain circumstances), TSO's parts manufacturing approval (P.MA), FAA-approved manufacturer's instructions, kits and service handbooks, ty .pe certificate data sheets, and aircraft specifications.  Other forms of approved data would be those approved by a designated engineering representative (DER), a manufacturer holding a delegation option authorization (DOA), STC'S, and, with certain limitations, previous FAA field approvals.  Supporting data such as stress analyses, test reports, sketches, or photographs should be submitted with the FAA Form 337.  These supporting data will be returned to the applicant by the local FAA district office since only FAA Form 337 is retained as a part of the aircraft records at Oklahoma City.

(3)	If additional space is needed to describe the repair or alteration, attach sheets bearing the aircraft nationality and registration mark and the date work was completed.

(4)	Showing weight and balance computations under this item is not required; however, it may be done.  In all cases where weight and balance of the aircraft are affected, the changes should be entered in the aircraft weight and balance records with the date, signature, and reference to the work performed on the FAA Form 337 that required the changes.

**GUIDANCE FOR FIELD  APPROVALS  **** **

**Notes:**
Note - The guidance in FAA Order 8300.10 is  mirrored in the
AWP-200 Working Agreement and the Alaska Alteration Handbook.
Some regional procedures have been added.
Data describing an article or appliance used in an alteration which is FAA-approved under a TSO.  As such, the conditions and tests required for TSO approval of an article are minimum performance standards.  The article may be stalled only if further evaluation by the operator (applicant) documents an acceptable installation which may be approved by the Administrator
Data in the -form of (TCA) Appliance Type Approval issued by the Minister of Transport Canada for those parts or appliances for which there is no current TSO available.  The TCA certificate is included within the installation manual provided with the appliance and includes the date of issuance and an environmental qualification statement.
Data describing a part or appliance used in an
alteration which is FAA-approved under a Parts Manufacturer Approval (PMA). (An STC may be required to obtain a PIMA as a means of assessing, airworthiness and/or performance of the part.)

## REMEMBER ! FIELD APPROVALS ARE NORMALLY USED FOR MAJOR ALTERATIONS

**REQUIRES  THE  SAME  DATA  AS  AN  STC**
**NOT  REQUIRING  DETAILED  ENGINEERING  ANALYSIS**
**NORMALLY  FOR  ONE  PRODUCT  ONLY;   **_**BY SERIAL NO....**_
**MAY REQUIRE ENGINEERING APPROVAL or ASSISTANCE**
**WILL  IT  REQUIRE  A  FLIGHT  MANUAL  SUPPLEMENT ?**
**WILL  AIRCRAFT  REQUIRE  A  FLIGHT  TEST ?**

## FSAW 98-03

**FLIGHT STANDARDS AIRWORTHINESS BULLETIN**
**To ensure that Instructions for Continued Airworthiness are provided for Major Alterations Approved Under the Field Approval Process**
**    ****EFFECTIVE DATE:  01-30-98**
**INSTRUCTIONS  MUST  BE  INCLUDED  ON  FAA  FORM 337**

**Notes:**
 Actual Copy of FSAW 98-03
BULLETIN TYPE:   Flight Standards Information Bulletin for Airworthiness (FSAW)  BULLETIN NUMBER:  FSAW  98-03
BULLETIN TITLE:  Instructions for Continued Airworthiness for Major Alterations Approved Under the Field Approval Process
    EFFECTIVE DATE:  01-30-98	 
1.	PURPOSE.  This bulletin establishes a Federal Aviation Administration (FAA) wide policy that will direct FAA aviation safety inspectors (ASI) , who are authorized to approve major alterations under the field approval process, to ensure that Instructions for Continued Airworthiness are provided for major alterations.
2.	BACKGROUND.  During discussion of Title 14 of the Code of Federal Regulations (14 CFR) part 135, single engine Instrument Flight Rules (IFR) passenger carrying rule, it was found that no policy existed to ensure that major alterations such as a stand-by electrical system or vacuum system, that could be approved under the field approval process, would be maintained to a published acceptable standard.  This policy will require field approvals for major alterations to match 14 CFR part 21, section 21.50 for at least one set of complete Instructions for Continued Airworthiness for each supplemental type certificate (STC) that was applied for after January 28, 1981.
3.	ACTION.  Airworthiness ASI's will ensure that each major alteration approved under the field approval process identified in FAA Order 8300.10, volume 2, chapter 1, will have at least one copy of Instructions for Continued Airworthiness prepared in accordance with 14 CFR parts' 23, 25, 27, 29, 31, 33, or 35; sections 23.1529, 25.1529, 27.1529, 29.1529, 31.82, 33.4, or 35.4, as applicable.  The Instructions for Continued Airworthiness will be documented on FAA Form 337, Major Repair and Alteration.  The Instructions will become a part of the aircraft's inspection and/or maintenance program for aircraft operated under this chapter.  The ASI shall ensure that the entry for the major alteration in the aircraft's maintenance records required by part 43, section 43.9 will also include a reference to the Instructions for Continued Airworthiness and identify FAA Form 337 where the instructions are documented.  The form will be kept in the aircraft's permanent records in accordance with part 91, section 91.417(2)(vi).
4.	INQUIRIES.  This bulletin was developed by Flight Standards, Aircraft Maintenance Division, AFS-300, General Aviation and Commercial Branch, AFS-340.  Any questions regarding this bulletin should be directed to AFS-340 at (202) 267-8203.
EXPIRATION.  This bulletin will expire on 01-31-99.

1.  PURPOSE.  This bulletin is in response to Federal Aviation Administration (FAA) field requests for guidance on what constitutes acceptable Instructions for Continued Airworthiness (ICA) for major alterations accomplished under a Field Approval, as addressed by Flight Standards Information Bulletin for Airworthiness FSAW 98-03.  This bulletin includes an ICA checklist which was developed using extensive regional office and field inspector input. 
A.  The purpose of the ICA is to provide instructions on how to maintain aircraft which are altered and appliances which are installed in accordance with a field approved major alteration. The ICA checklist is a guide for both the applicant who creates the ICA and the FAA Flight Standards inspector who accepts the ICA.  The ICA developed in accordance with this guidance constitutes methods, techniques and practices "acceptable" to the Administrator.  If the ICA for the submitted field approval major alteration is not acceptable to the FAA inspector, that inspector should not sign Block 3 of the applicant’s FAA Form 337, Major Repair and Major Alteration. 
B.  The purpose of the ICA being addressed in Block 8 of 
Form 337 is to provide the aircraft owner/operator with the following three advantages:
(1)  The major alteration and reference to ICA are contained in one document;
(2)  The ICA becomes a permanent aircraft record as 
required by Title 14 of the Code of Federal Regulations (14 CFR), section 91.417(a)(2)(vi); and
(3)  The owner/operator can contact FAA registry for a replacement FAA Form 337 if the ICA is lost or destroyed.  The additional reference to the presence of ICA as part of the major alteration in the aircraft’s maintenance entry, will ensure that maintenance personnel appropriately address ICAs during future inspections.
