U. S. Department of Transportation Docket Operations, M-30 West Building ground floor,

Room W12-140 1200 New Jersey Avenue, SE Washington DC, 20590

SUBJECT: Exemption No. 4050P from 14 CFR 91.9(a), 14 CFR 91.531(a)(1), 14 CFR 91.531(a)(2)

REFERENCE: Regulatory Docket No. FAA-2002-11491

This letter submits the petition of Cessna Aircraft Company for the extension of Exemption No. 4050, Regulatory Docket No. FAA-2002-11491 (formerly Regulatory Docket No. 23771), that is presently due to expire on 31 March 2010.

Exemption No. 4050 provides qualifying pilots of Cessna Citation Model 550, S550, 552, and 560 airplanes relief from §§91.9(a) and 91.531(a)(1) & (2) of Title 14, Code of Federal Regulations (14CFR) that enables them to operate without a pilot who is designated as second in command.

Cessna would like the FAA to consider at least a thre e-year extension of the Ex emption as granted by FAA letter dated 23 January 2006 for Revision “N” to this Exemption. (A copy is attached)

The justifications, safety assurance, and public interest remain as presented in the previous petitions to this Docket, beginning with Cessna’s letter of petition dated 15 September 1983. Also, the safety record of pilots operating under the provisions of Exemp tion No. 4050 continues to remain clear of accidents or incidents. This is confirmed in the analysis of operations conducted under Exemption No. 4050 as requested by item 17 of same exemption. The analysis is as follows:

Operational Exposure Since issuance of Exemption No 4050 in June 1984, 1172 pilots have completed the requirements and have received a waiver to operate Citation II, Citation S/II, Citation Bravo, Citation V or Citation Ultra and Citation Encore & Citation Encore+ aircrafts as a single pilot at weights above 12,500 pounds.

1. There have been no reported accidents or incidents involving these pilots.

2. Operations conducted as single pilot have been “normal”. Passenger carrying IFR route profiles have been flown to normal destinations, including routine operations in and out of terminal control areas and high-density traffic areas. These pilots conduct essentially the same operational flights as pilots operating single pilot certified Model 501 and 551 airplanes.

3. As of December 2011 these pilots have reported flying a total of approxima tely 221,976 hours and 187,107 landings with one pilot in the cockpit.

During this same period of time (J une 1984 to December 20 11), there have been 1,964,007 hours flown by Model 501 aircraft and 525,361 hours flown by Model 551 aircraft.L390-12-0473

Accident/Incident Data There have been no reported accidents or incidents involving these pilots qualified and operating under Exemption No. 4050.

Known Problems The only problem area encountered with this exemption program is that pilots who operate 550, S550 or 560 airplanes as single pilots under the exemption must pa y in excess of $10,000.00 more per year for recurrent training than the 501 or 551 pilot who operates in the same environment.

Conclusion

1. There have been no reported accidents or incidents involving single pilot crew operated Citation aircraft in this reporting period.

2. The Safety record of single pilot operated Citation aircraft is equivalent to or better than any other jet or turboprop aircraft.

3. As stated in Cessna’s Application for Exemption, there is no operational pilot workload difference between a Citation Model 551 at 12,5000 lbs or a Citation Model 560 at 16,300 lbs.

Cessna understands the FAA presently has substantia l data accumulations in Docket FAA-2002-11491 (Formerly Docket 23771) to support Cessna’s presen t petition for the Extension of Exemption No. 4050. However, Cessna would be pleased to present any add itional available data needed by FAA to process this petition.

In closing, Cessna continues to thank FAA for their consideration of previous petitions in the subject Docket and we are hopeful of FAA’s grant of the exemption extension requested in this letter.

Sincerely,

for Carlos Ayala Manager - Airworthiness Cessna Aircraft Company
