SA83NE Single Configuration

PETITION FOR EXEMPTION

The Leading Edge Group, LLC (LEG), as FAA Supplemental Type Certificate (STC) holder of

SA83NE requests FAR compliance relief and submits this Petition for Exemption (PIE) to FAA

rule making established under 14 CFR Sect. 26.47(c) & (e)(2).

LEG petitions for US Govt. engineering relief on single tank Configuration of SAB3NE for

B737-200 series aircraft, with LEG/pats Auxiliary Fuel System (AFS) in VIP passenger cabin

(LOPA) deck plans.

Boeing SNs 22431 & 22628:

1. These SNs contain a VIP stateroom and are configured for HOS service.

2. These SNs operate exclusively in private or Head of State (HOS) service.

3. These SNs are listed on US-FAA and foreign Registries.

4. These SNs will require extensive engineering changes for a deck plan (LOPA) to be

suitable for EASA or US commercial revenue service under FAR 121 (125 or 135).

S. Responsive engineering resources of the FAA can be conserved and financial relief

can be realized on behalf of the OAH and US Govt; upon timely approval of this PIE.

6. The Operators nor STC holder are able to determine if modifications to the AFS

loading points on this airframe have been altered, AFS brackets removed or, if the AFS

attach points have been adapted for other purposes; requiring in themselves new lCAs.

7. Operator disclosure and OAH-onboard AFS survey of the aircraft is required to submit

useful engineering for FAA that is relevant to SN existing condition.

8. It is the position of the STC holder that air safety will not be adversely impacted given

these SNs have limited private use and, each at over 3D-years of airframe age, will likely

never return to commercial FAA/EASA air carrier service.

In the event any of these SNs are transferred to a third party and an interior reconfiguration

(LOPA) is completed, a current airframe survey to include #6 changes can be reviewed and

specific airframe load and inspection analysis (OTE Ion) due FAA under the Aging Aircraft

Safety Rule for the AFS (and the attach points) can be completed in accordance with FAR

26.47(c) and (e)(2).

to FAA rule making established under 14 CFR Sect, 26.47(c) & (e)(2).

LEG petitions for US Govt, engineering task relief on a single tank Configuration of

SA83NE for 6737-200 series aircraft, with LEG/pats Auxiliary Fuel System (AFS) in VIP

passenger cabin (LOPA) deck plans.

3. These SNs are listed on FAA and foreign Registries.

4. These SNs will require extensive engineering changes for a deck plan (LOPA)

to be suitable for EASA or US commercial revenue service under FAR 12L

5. Responsive engineering resources of the FAA can be conserved and financial

relief can be realized on behalf of the DAH and US Government; upon timely

approval of this PIE.

6. The Operator nor STC holder are not able to determine if modifications to the

AFS loading points on this airframe have been altered, AFS brackets removed or,

if the AFS attach points have been adapted for other purposes; requiring in

themselves new lCAs.

7. Operator disclosure and DAH~onboard AFS survey of the aircraft is required to

submit useful engineering to FAA that is relevant to SN existing condition.

8. It is the position of the STC holder that air safety will not be adversely

impacted given these SNs have limited private use and with over 30-years of

airframe age, will likely never return to commercial FAA/EASA air carrier service.

In the event these SNs are transferred to a third party and an interior reconfiguration

(LOPA) is completed, a current airframe survey to include #6 changes can be reviewed

and specific airframe load and inspection analysis (DTE I DTI) due FAA under the Aging

Aircraft Safety Rule for the AFS (and the attach points) can be completed in accordance

with FAR 26.47(c) and (e)(2).

Thank you.
