FAA Instrument Flight Instructor (FII)Instrument RegulationsMedium
During an IFR flight in IMC, a pilot experiences a sudden cabin pressurization failure and deviates from an assigned ATC clearance by descending immediately without prior clearance to resolve the emergency. Under 14 CFR 91.3(b), what is the pilot required to do?
- ASubmit a written report of the deviation to the Administrator if requested by ATC or the FAA.
- BFile a report with the NTSB within 10 days regardless of whether it is requested.
- CNotify the nearest FSDO by telephone within 24 hours in every case.
- DNothing further is required since 91.3(b) grants unconditional immunity for emergency deviations.
Show answer & explanationAnswer & explanation
Correct answer: A. Submit a written report of the deviation to the Administrator if requested by ATC or the FAA.
14 CFR 91.3(b) allows the PIC to deviate from any rule to the extent required to meet an emergency, but 91.3(c) requires a written report to the Administrator only if requested by ATC or the FAA, describing the emergency and the deviation.
Why the other options are wrong
- B. NTSB reporting under Part 830 applies to accidents/incidents meeting specific criteria, not simply emergency deviations.
- C. There is no automatic 24-hour telephone notification requirement solely for an in-flight emergency deviation.
- D. Emergency authority does not eliminate the possibility of being asked for a written report.
Emergency Authority (91.3)
91.3(b) permits the PIC to deviate from any regulation to the extent necessary to meet an in-flight emergency; a written report may be required afterward if requested.
- PIC has final authority and responsibility for the aircraft
- Deviation authority applies only 'to the extent required' by the emergency
- Written report required only if requested by ATC/Administrator per 91.3(c)
Memory trick: 'Emergency bends the rules, but paperwork follows if asked.'
