Regulatory Docket No. FAA-2009-0444 

Mr. Carlos Ayala 

Manager, Airworthiness 

Cessna Aircraft Company 

One Cessna Boulevard/P.O. Box 7704 

Wicliita, Kansas 67277-7704 

Dear Mr. Ayala: 

This letter is to inform you that we have granted your petition to extend Exemption No. 9906A. 

It explains the basis for our decision and describes its effect. 

The Basis of Our Decision 

By letter dated October 13,2010, (Ref: L390-10-3333) you petitioned the Federal Aviation 

Administration (FAA) on behalf of Cessna Aircraft Company (Cessna) for an extension of 

Exemption No. 9906 A. That exemption fi-om § 23.979(b)(2) of Title 14, Code of Federal 

Regulations (14 CFR) permits Cessna to receive type certification approval of the Model 525C 

series aiiplanes with a non-compliant type design for the pressure refueling panel for a limited 

time. 

In yotir petition, you indicate that the global economic conditions have significantly impacted the 

aviation industry business; resulting in Cessna recently reducing its labor force. Therefore, 

Cessna requests an eirtension, to May 1, 2011, of the time limit for incorporation into production 

line requirements of a pressure refueling panel fully compliant with the requirements of 

§ 23.979(b)(2), and until May 1, 2012 for retrofit of all fielded Model 525C series airplanes. 

The FAA has determined that good cause exists for not publishing a summary of the petition in 

the Federal Register because the requested extension of the exemption would not set a precedent 

and any delay in acting on this petition would be detrimental to Cessna. 
Our Decision: 

Tlie FAA has determined that the justification for the issuance of Exemption No. 9906 A, remains 

valid with respect to this exemption and is in the public interest. 

Therefore, under the authority provided by 49 U.S.C. 40113 and 44701, which the FAA 

Administrator has delegated to me, I grant your petition. 

The Effect of Our Decision 

Our decision extends the termination date of Exemption No. 9906A to May 1,2011, unless 

superseded or rescinded. For the Model 525C airplanes, the exemption as extended is subject to 

the following conditions and limitations: 

1. Cessna Aircraft Company must certify and incorporate into the production line 

requirements a pressure refueling panel, fully compliant with tlie requirements of 

§ 23.979(b)(2), into the Model 525C aiqsknes no later than May 1, 2011. 

2. Cessna Aircraft Company must retrofit the Model 525C airplanes delivered under the 

terms of the exemption with the new pressure refiieling panel described in Condition 1 

above no later than May 1, 2012. 

3. Until the incorporation of the changes required in the above Conditions 1 and 2 of this 

exemption have been completed, Cessna Aircraft Company must display a placard at 

each of the refueling stations and add to the airplane flight manual (AFM) "Limitations" 

section for the Model 525C airplanes the limitation prohibiting any kind of vehicle or 

equipment inside defined, areas of fiiel vent discharge during airplane refueling 

operations. 

4. For airplanes subject to Condition 2 of this exemption, the operating limitations section 

of the airplane flight manual (AFM) must include the following statement: 

"No person may operate this airplane after May 1,2012, unless the 

pressure refueling panel has been modified in accordance with the tenns 

of Exemption No. 9906 A." 

This statement may be removed from the AFM after the required modification has been 

made. 

All other conditions and limitations of Exemption No. 9906 A remain the same. This letter must 

be attached to, and is a part of, Exemption No. 9906A. 

Sincerely, 

Earl Lawrence
