FAR 91.1415 Mechanical Reliability Reports

FAR 91.1415 requires fractional ownership program managers under a CAMP to report aircraft failures, malfunctions, and defects. Learn what, when, and how.

In Plain English

FAR 91.1415 applies to program managers of fractional ownership operations who maintain aircraft under a Continuous Airworthiness Maintenance Program (CAMP). It requires written reports of specific in-flight failures, malfunctions, and defects so the FAA can spot safety trends across the fleet.

Reportable events include:

  • In-flight fires (and whether fire-warning systems worked), false fire warnings, or fires not covered by warning systems
  • Engine shutdowns from flameout, damage, foreign object ingestion, icing, or multiple-engine shutdowns
  • Exhaust, fuel, propeller feathering, or landing gear malfunctions during flight
  • Smoke, vapor, or toxic fumes in the cabin
  • Brake loss on the ground, structural cracks/corrosion beyond limits, or any structure needing major repair
  • Any system failure that forces emergency action in flight (other than engine shutdown)

Reports cover each 24-hour period starting at 0900 local and must be sent within 72 hours to the issuing Flight Standards office. The manager must also report any other defect they believe endangers safe operation, and supplement reports as new information arrives. Reports cannot be withheld just because some information is missing.

Regulation Text
14 CFR § 91.1415
§ 91.1415 CAMP: Mechanical reliability reports. (a) Each program manager who maintains program aircraft under a CAMP must report the occurrence or detection of each failure, malfunction, or defect in an aircraft concerning— (1) Fires during flight and whether the related fire-warning system functioned properly; (2) Fires during flight not protected by related fire-warning system; (3) False fire-warning during flight; (4) An exhaust system that causes damage during flight to the engine, adjacent structure, equipment, or components; (5) An aircraft component that causes accumulation or circulation of smoke, vapor, or toxic or noxious fumes in the crew compartment or passenger cabin during flight; (6) Engine shutdown during flight because of flameout; (7) Engine shutdown during flight when external damage to the engine or aircraft structure occurs; (8) Engine shutdown during flight because of foreign object ingestion or icing; (9) Shutdown of more than one engine during flight; (10) A propeller feathering system or ability of the system to control overspeed during flight; (11) A fuel or fuel-dumping system that affects fuel flow or causes hazardous leakage during flight; (12) An unwanted landing gear extension or retraction or opening or closing of landing gear doors during flight; (13) Brake system components that result in loss of brake actuating force when the aircraft is in motion on the ground; (14) Aircraft structure that requires major repair; (15) Cracks, permanent deformation, or corrosion of aircraft structures, if more than the maximum acceptable to the manufacturer or the FAA; and (16) Aircraft components or systems that result in taking emergency actions during flight (except action to shut down an engine). (b) For the purpose of this section,means the period from the moment the aircraft leaves the surface of the earth on takeoff until it touches down on landing. (c) In addition to the reports required by paragraph (a) of this section, each program manager must report any other failure, malfunction, or defect in an aircraft that occurs or is detected at any time if, in the manager's opinion, the failure, malfunction, or defect has endangered or may endanger the safe operation of the aircraft. (d) Each program manager must send each report required by this section, in writing, covering each 24-hour period beginning at 0900 hours local time of each day and ending at 0900 hours local time on the next day to the Flight Standards office that issued the program manager's management specifications. Each report of occurrences during a 24-hour period must be mailed or transmitted to that office within the next 72 hours. However, a report that is due on Saturday or Sunday may be mailed or transmitted on the following Monday and one that is due on a holiday may be mailed or transmitted on the next workday. For aircraft operated in areas where mail is not collected, reports may be mailed or transmitted within 72 hours after the aircraft returns to a point where the mail is collected. (e) The program manager must transmit the reports required by this section on a form and in a manner prescribed by the Administrator, and must include as much of the following as is available: (1) The type and identification number of the aircraft. (2) The name of the program manager. (3) The date. (4) The nature of the failure, malfunction, or defect. (5) Identification of the part and system involved, including available information pertaining to type designation of the major component and time since last overhaul, if known. (6) Apparent cause of the failure, malfunction or defect (for example, wear, crack, design deficiency, or personnel error). (7) Other pertinent information necessary for more complete identification, determination of seriousness, or corrective action. (f) A program manager that is also the holder of a type certificate (including a supplemental type certificate), a Parts Manufacturer Approval, or a Technical Standard Order Authorization, or that is the licensee of a type certificate need not report a failure, malfunction, or defect under this section if the failure, malfunction, or defect has been reported by it under § 21.3 of this chapter or under the accident reporting provisions of part 830 of the regulations of the National Transportation Safety Board. (g) No person may withhold a report required by this section even when not all information required by this section is available. (h) When the program manager receives additional information, including information from the manufacturer or other agency, concerning a report required by this section, the program manager must expeditiously submit it as a supplement to the first report and reference the date and place of submission of the first report.

Oral Exam Questions a DPE Might Ask
Q1Who must file mechanical reliability reports under FAR 91.1415, and what kinds of events trigger a report?
Per FAR 91.1415(a), each program manager maintaining fractional program aircraft under a CAMP must report failures, malfunctions, or defects such as in-flight fires, engine shutdowns, fuel or gear system problems, structural damage requiring major repair, and any defect requiring emergency action in flight.
Q2What is the deadline for submitting a mechanical reliability report?
FAR 91.1415(d) requires reports covering each 24-hour period (starting at 0900 local) to be mailed or transmitted within 72 hours to the Flight Standards office that issued the program manager's management specifications, with allowances for weekends and holidays.
Q3If the program manager doesn't yet have all the required information, can they delay the report?
No. FAR 91.1415(g) states no person may withhold a required report even when not all information is available, and FAR 91.1415(h) requires supplemental reports to be submitted expeditiously when additional information is received.
