- 0482 CAF Petition for Exemption From 91.319(c) of Title 14, Code of Federal Regulations Exemption No. 10853

### Mr. Stenevik,

As discussed, below are some questions to assist in an Equal level of Safety (ELoS) for N529B as required by 14 CFR Part 11 and usin g a SMS

- based process. We put together these questions so as to have a structured starting point or baseline for this process. By definition, ensuring an adequate level of safety in this case, is a two

- way street which requires the operator’s input, adju stments, and alternatives. If any other issues come up, we’ll pass them along as well. If this concept is workable, the format can be adjusted to the B

- 24 as well.

Please call if you have any questions or if any issue requires clarification. I can be reached at (202) 385

- 9634.

Thanks

Miguel Vasconcelos Aviation Safety Analyst AFS

- 830 FAA

- HQ Initial ELoS Questions (B

- 29)

1. What are the design and manufacturing features of the B

- 29 that create hazardous conditions which could impact people and property being overflown which would not be found by the operation of a similar civil type, i.e. DC

- 7?

2. What safety data do you have concerning the aircraft while in service such as accident rate and types and classification of accidents? In other w ords, what failed and what is likely to fail, and how, and what is being done to mitigate these.

3. How have you incorporated the applicable Air Force Regulations and SOPs (operational) applicable to the B

- 29 to CAF’s operations?

4. What is the tec hnical substantiation for the modifications to the R

- 3350 engines (

- 95 Powercase &

- 26 Blower) installed in the aircraft? Please submit a copy of these materials to include a reliability analysis, proving & validation test data.

5. How were engine

- rel ated issues in the C

- 119 and Douglas AD

- series considered? Was the

- 95 and the

- 26 option chosen because these were available andaffordable or because a civil certificated version of the powerplant was not technically possible? Please explain.

6. What is the modification status of the aircraft? Please submit relevant records, especially those made to the aircraft after it was grounded in 2006?

7. What is being done to address the recent deficiencies (Aug 2014) which resulted in the FSDO not acc epting the AIP for N529B?

8. Can you provide a listing and data showing that all applicable USAF T.Os and TCTOs (to end of operational service) have been complied with?

9. What ADs, SBS, or other civil requirement/guidance applicable to the R

- 3350s and the propellers installed in N529B have been considered? In other words, what safety issues were addressed in the civil side are relevant to enhancing the safety of N529B?

10. What are all of the applicable USAF T.Os for the aircraft in effect at the time of retirement?

11. What flight emergencies, in

- flight failures, and post

- flight discrepancies have occurred since the aircraft returned to airworthy condition in August 2010?

12. Is the fire detection and suppression system functional and properly i nspected?

13. What is the SOAP frequency and results since August 2010?

14. What are the details of the aging aircraft and corrosion control programs in place?

15. What are the configurations and redundancies installed in the aircraft?

16. The expectation is that the most experienced crew would be used. As such, can you please provide the qualifications and experienced of the proposed crew for the flight?

17. Can you provide information showing that the FE in the B

- 29 properly rated?

18. What special pre

- flight and post

- flight inspections can be performed to enhance safety?

19. What QC processes are used in addressing supplier and parts acquisition and use?

20. Has the CAF implemented SMS/CRM/MRM/ORM? If so, please provide details.

21. On the issue of engine/powerplant and propeller failure and related issues, please provide the mitigating strategies for the following:

 Engine Failure & Fire (Including Overheating, Magnesium Components, Accessory Drave Shaft, PRTs, Low Compression, V alves (e.g., Pounding), Cylinders, Metal in Sumps); APU Fire & Containment;

 Propeller Overspeed and Separation;

 Hydraulic & Electrical Failures;

 Tail Strike and Landing Gear Failure;

 MEL & Flight Abort Criteria;

22. What coordination has b een done with other Military/Federal entities concerning the proposed overflight?

23. For flight over populated areas, please discuss and provide detail on the following:

 Egress/Ingress (Airports & Areas);

 Ground References & Landmarks;

 Formation, Mixed Formation, and In

- Trail;

 Lateral Separation & Maneuvering Room;

 Straight & Level, Minimum Maneuvering;

 Rehearsal, if Special Event is Involved;

 Performance, e.g., (1) minimum airspeed for which it is still possible to climb away, without change of configuration, if any one engine fails, (2) symmetrical thrust should be maintained at all times, and power changes minimized, (3) glide ratio.

 In

- Flight Divert Procedures Including Divert Airports (e.g. DCA, An drews AFB) and Crash Landing Areas (e.g. Potomac River);

 Reduced operating weight, power settings;

### Good Afternoon Miguel;

I’m glad we talked on the phone about this, however, it still looks like it is going to take many pages and lots of documents. I will attempt to put the information in a format to make review as easy as possible. However, while I am doing this, please send me any additional requirements/questions as soon as you get them. That way I can have some continuity when putting this together.
