Safety Recommendation A-22-009

We note that, although Textron Aviation has agreed to voluntarily update future derivative Cessna 560XL airplane models to include a parking brake indication, you do not plan to require that newly manufactured Cessna 560XL airplanes comply with the updated parking brake standard in Title 14 CFR 25.735.

We are encouraged by Textron’s plan to voluntarily incorporate a parking brake indication in its next approved derivative Cessna 560XL airplane model. We are concerned, however, that newly manufactured Cessna 560XL airplanes, which are also included in this recommendation, are still not required to comply with the updated parking brake standard. Therefore, we urge you to address newly manufactured airplanes, as recommended. In the meantime, pending our review of a plan to address this concern, Safety Recommendation A-22-9 is classified OPEN-- UNACCEPTABLE RESPONSE.

-From Kathryn B. Thomson, Deputy Administrator: The FAA has continued to pursue the appropriate level of safety regarding this recommendation in partnership with Textron Aviation Inc. As a result, Textron Aviation Inc. agreed to voluntarily update future derivative Cessna 560XL airplane models to include an indication for the parking brake. The certification scope of the project was determined not to be significant under Title 14 Code of Federal Regulations (CFR) Part 21, Section 21.101, Designation of applicable regulations, Paragraph (b)(1).

Consequently, the certification basis of the Cessna 560XL airplane may remain at the originally certified amendment level for the changed areas, even though the new design would be compliant with the cockpit indication requirement in 14 CFR 25.735(d), Parking Brake, at amendment 25-107.

Based upon these findings, and per the risk assessment results associated with A-22-8, the FAA determined not to mandate compliance with 14 CFR 25.735, amendment 25-107 for newly manufactured Cessna 560XL airplanes. However, we will continue to update the Board on Textron Aviation’s progress on incorporating a parking brake annunciation in the next approved derivative airplane model.

I believe the FAA has effectively addressed Safety Recommendation A-22-8 and consider our actions complete. I will keep the Board informed of the FAA’s progress on Safety Recommendations A-22-9 and anticipate providing an update by August 31, 2024.

We note that you intend to work with Textron Aviation to assess the safety issues related to the Cessna 560XL. We believe this is a necessary first step to responding to these recommendations. Pending our receipt and review of additional information regarding how you plan to address the specific actions described in each of these recommendations, Safety Recommendations A-22-8 through -10 are classified OPEN--ACCEPTABLE RESPONSE.

-From Billy Nolen, Acting Administrator: The Federal Aviation Administration (FAA) is analyzing these safety recommendations to develop an appropriate action plan, which will include working with Textron Aviation to assess the Cessna 560XL in response to the issues identified in these safety recommendations.

I will keep the Board informed of the FAA’s progress on Safety Recommendations A-22-8 through -10, and anticipate providing an update by August 31, 2023.

The attached letter from the NTSB Chair provides information about the NTSB’s May 4, 2022, report Require Safeguards to Prevent Cessna 560XL Takeoff with Parking Brake Engaged, AIR-22-06. The details of this accident investigation and the resulting safety recommendations may be found in the attached report, which can also be accessed at http://www.ntsb.gov.

The NTSB is vitally interested in these recommendations because they are designed to prevent accidents and save lives. We would appreciate a response within 90 days of the date of this letter, detailing the actions you have taken or intend to take to implement these recommendations. When replying, please refer to the safety recommendations by number (for example, A-22-8 and A-22-9). We encourage you to submit your response to ExecutiveSecretariat@ntsb.gov.

Please do not submit both an electronic copy and a hard copy of the same response.

This letter provides information about the National Transportation Safety Board’s (NTSB) May 4, 2022, report Require Safeguards to Prevent Cessna 560XL Takeoff with Parking Brake Engaged, AIR-22-06. The details of this accident investigation and the resulting safety recommendations may be found in the attached report, which can also be accessed at http://www.ntsb.gov.

As a result of this investigation, we identified the following safety issues:

• Without a parking brake indication, some Cessna 560XL pilots may not recognize that the parking brake is not fully released and attempt to take off, which could result in a runway overrun. • A checklist item before takeoff is initiated would aid pilots of Cessna 560XL airplanes in ensuring the full release of the parking brake before the takeoff roll and prevent hazardous runway overruns. Accordingly, the NTSB makes the following safety recommendations to the Federal Aviation Administration:

Issue an airworthiness directive for in-service Cessna 560XL airplanes to require that they meet the parking brake indication requirements of Amendment 25-107 of Title 14 Code of Federal Regulations
