14 CFR 121.377 — Maintenance and Preventive Maintenance Training Program
Requires airlines to establish and maintain an FAA-approved training program for all maintenance and preventive maintenance personnel.
Regulation Text
Each certificate holder shall establish and maintain an FAA-approved maintenance training program that provides instruction sufficient to ensure that each person performing maintenance, preventive maintenance, or alterations is competent to perform assigned duties.
Note: This is an excerpt. Refer to the full regulation in eCFR for the complete text.
Plain-English Explanation
Airlines must have FAA-approved training programs for all maintenance personnel. This goes beyond having A&P certificates — mechanics must receive airline-specific training on the aircraft types they maintain, company procedures, and human factors. Initial and recurrent training is required. This regulation reflects the complexity of airline maintenance operations where a single error can affect hundreds of passengers.
