CAMP Mechanical Interruption Reports

FAR 91.1417 — CAMP Mechanical Interruption Reports

FAR 91.1417 requires fractional ownership program managers under a CAMP to file monthly mechanical interruption summary reports for multiengine aircraft.

In Plain English

FAR 91.1417 applies to fractional ownership program managers who maintain their aircraft under a Continuous Airworthiness Maintenance Program (CAMP). It sets a recurring reporting duty so the FAA can track patterns of mechanical issues that don't rise to the level of the more serious failures covered by § 91.1415.

By the end of the 10th day of each month, the program manager must mail or deliver a summary report to the Flight Standards office that issued their management specifications, covering the previous month's events in multiengine aircraft:

Each flight interruption, unscheduled aircraft change en route, or unscheduled stop or diversion caused by known or suspected mechanical problems — but only if the event isn't already reportable under § 91.1415.
The number of in-flight propeller featherings, broken out by propeller type, engine, and aircraft.
Featherings done for training, demonstration, or flight checks are excluded.

Why it matters: these reports help the FAA spot reliability trends in fractional fleets before they become safety issues.

Oral Exam Questions a DPE Might Ask

Q1Who is required to file a mechanical interruption summary report, and to whom is it sent?

Under FAR 91.1417, each fractional ownership program manager who maintains program aircraft under a CAMP must send the summary to the Flight Standards office that issued the program manager's management specifications.

Q2What is the deadline for submitting the mechanical interruption summary report?

FAR 91.1417 requires the report to be mailed or delivered before the end of the 10th day of the month following the month being reported.

Q3Do you have to report every propeller feathering on the summary report?

No. FAR 91.1417(b) requires reporting in-flight propeller featherings by propeller, engine, and aircraft type, but featherings performed for training, demonstration, or flight check purposes are excluded.
