CBO Safety Guidelines - Post-flight Safety
Verified from official sourcesAC 91-57C ¶ 3.3.2.1Version 2Effective -Verified 29 August 2026
In plain language
After flying, you should review the flight for any safety risks, remove the batteries, and secure the aircraft according to manufacturer recommendations.
Requirement as structured
The FAA recommends that CBO safety guidelines encourage flyers to review flights for unplanned risks and safely secure the UA, including removing batteries and protecting fragile parts.
Original regulatory text
The FAA recommends including information on the five hazardous attitudes in aeronautical decision making (refer to the Pilot’s Handbook of Aeronautical Knowledge, Figure 2-4) and the “Dirty Dozen” human behaviors in aircraft maintenance (refer to https://www.faasafety.gov/files/gslac/library/documents/2012/Nov/71574/ DirtyDozenWeb3.pdf). 4. Airspace restrictions and prohibitions. The FAA recommends that safety guidelines provide information to recreational flyers on how to become aware of all restricted and prohibited airspace. The guidelines should also emphasize that Federal law requires each member to comply with all airspace restrictions and prohibitions applicable to the airspace in which the operation will occur. Refer to 49 U.S.C. § 44809(a)(5) and (6). 5. Preflight safety. To mitigate hazards, the FAA encourages CBOs to include in their guidelines, as appropriate, information concerning preflight assessments, flight planning, hazard identification techniques, and scanning techniques for aircraft and other people entering an area of operation. AC 107-2, Appendix E, Sample Preflight Assessment and Inspection Checklist, provides a detailed example of a preflight checklist that CBOs may consider adapting for their particular needs. CBOs may also choose to develop a through-flight or turnaround checklist for preflight inspections between successive flights that are flown back-to-back. Such a preflight checklist could cover those items that should be checked before flight, such as confirmation of general condition or that control surfaces are functioning. 6. In-flight safety. The FAA recommends that guidelines for in-flight safety remind recreational flyers to assess the performance of the UA continually; monitor the strength of command and control links; watch for changing weather conditions; and watch for unexpected people or aircraft in the area of operation. Additionally, the FAA recommends that guidelines instruct recreational flyers to be familiar with the automated features a UA may have, and how the UA would behave when those features are activated. For instance, it is important that operators know that a return-to-home protocol on a UA could initiate a straight-line path 10/20/22 AC 91-57C 3-4 toward the person operating it that could cross over people or possibly strike an obstacle such as a tree or power lines. 7. Post-flight safety. Guidelines for post-flight inspection may include encouraging recreational flyers to review the flight and consider whether any unplanned events occurred that presented a risk. Guidelines may also include recommendations for safely securing UA between flights to include removing batteries and protecting fragile parts from wear and tear per the manufacturer’s recommendations (if applicable).
