Tell me about yourself and your experience as an aircraft mechanic

Start with your current role, your certifications, and the most relevant experience for the job you are applying for, focusing on the last five to ten years. Mention specific ratings such as A&P, powerplant, or airframe, and any type ratings, then tie those credentials to the duties listed in the job description. Give a concise work example that highlights your hands-on skills and responsibility, such as a recent inspection program you supported or a complex repair you completed. Describe the aircraft type, the scope of work, and the safety checks you performed so the interviewer can picture your daily tasks. Keep this summary to about two minutes in delivery and practice so it sounds natural rather than rehearsed. Avoid reciting your entire resume or going back to unrelated early jobs unless they directly support the role.

How do you approach troubleshooting an in-flight engine vibration report

Explain a systematic approach that starts with gathering maintenance logs and pilot reports, then moves to visual inspection, borescope if needed, and component checks based on likely causes. Emphasize following the maintenance manual and airworthiness directives before making repairs and documenting each step for traceability. Give a specific example where you diagnosed vibration caused by an unbalanced propeller or a worn engine mount, describing the inspection steps, tools used, and how you isolated the root cause. Mention using vibration-analysis data or run-up testing to confirm the fix so the interviewer sees the technical sequence. Highlight common pitfalls to avoid, such as replacing expensive parts without confirming the root cause or skipping follow-up testing after repairs. Stress the importance of thorough documentation and coordination with the flight crew and certifying inspector when required.

Describe your experience with FAA regulations, airworthiness directives, and maintenance records

Tell the interviewer you track applicable FARs, review airworthiness directives for affected models, and ensure maintenance records meet regulatory requirements. Explain your routine for checking Service Bulletins and AD compliance during inspections so nothing is missed before return to service. Provide a concrete example where you found a recurring AD requirement during scheduled maintenance and created a checklist to ensure every aircraft in the fleet met the requirement. Describe how you updated the logbooks and coordinated with quality assurance to prevent compliance drift. Note that sloppy paperwork can ground an aircraft or create liability, so emphasize accuracy and timely entries. Avoid assumptions about compliance and always verify historical entries before signing off work.

How do you perform a pre-flight or daily inspection for a single-aisle aircraft

Outline a standard inspection sequence tied to the maintenance manual or company checklist, covering airframe, control surfaces, landing gear, fluid levels, and safety equipment. Stress following the checklist step by step and using calibrated tools for torque and fluid checks to maintain consistency. Offer an example of a daily inspection where you discovered a leaking hydraulic line during a walk-around and how you isolated the system, reported the discrepancy, and arranged a controlled repair before flight. Describe the communication steps with dispatch and the paperwork you completed to document the defect and corrective action. Remind the interviewer that the goal is safety and airworthiness, so never skip steps to save time. Avoid informal shortcuts and be ready to explain any deviation from standard procedure during the interview.

What tools and test equipment are you most comfortable using

List common hand tools, torque wrenches, borescopes, multimeters, vibration analyzers, and any specialized engine test stands you have used, and explain how you keep them calibrated. Emphasize familiarity with the tools specified in the maintenance manual for the aircraft types you work on and your process for tool control to prevent FOD. Describe a situation where a borescope inspection or vibration analyzer produced data that changed your repair plan, explaining how the measurements guided your decision. Include notes on tool maintenance, such as calibration schedules and checklists, to show you value accuracy. Stress that proper tool control prevents damage and safety issues, and explain any personal systems you use to track calibration dates. Avoid claiming experience with equipment you have not actually used, and be ready to explain training you would take for unfamiliar gear.

How do you prioritize maintenance tasks when multiple aircraft need attention

Explain a prioritization method that balances safety-critical defects, regulatory compliance, operational needs, and available resources. Mention using MELs, dispatch requirements, and coordination with operations to determine which aircraft must be grounded and which can be deferred under a proper engineering or MEL procedure. Share an example where you prioritized a control surface discrepancy over cosmetic repairs before a planned flight, describing how you communicated with the dispatcher and adjusted manpower to meet the highest safety priorities. Highlight any logbook entries and approvals that were obtained to document the decision. Make clear that safety and legality are the deciding factors when prioritizing work, and that you escalate when decisions impact dispatchability. Avoid appearing to favor convenience or schedule over compliance.

Explain how you inspect and repair landing gear systems

Describe a stepwise inspection covering visual checks for wear, corrosion, hydraulic lines, retraction tests, and torque checks on fasteners, following the manufacturer's procedures. Include the process for removing, disassembling, and replacing bearings or actuators when limits are exceeded, and stress the use of proper jacking procedures and safety stands. Provide a real example where you replaced a worn shock strut seal and performed a functional retraction test, then recorded the service in the logbook and coordinated a leak check during taxi. Mention the use of service manuals and any special tools required for bearing preload or torque calibration. Warn against skipping post-repair functional tests, because a missed test can lead to landing incidents. Emphasize proper safety precautions when working under jacked aircraft and the importance of tagout procedures.

How do you stay current with technical manuals, service bulletins, and new procedures

Explain a routine where you review fleet maintenance bulletins, manufacturer updates, and regulatory notices at established intervals and maintain an indexed system for quick reference. Mention using digital library tools or company distribution lists to ensure you receive and read new releases as they come in. Give an example of implementing a new service bulletin procedure across the hangar after receiving training, describing how you briefed teammates and updated standard job cards to reflect the change. Note if you participate in recurrent training or team briefings to reinforce new practices. Stress that reading documents is not enough, you must apply them and update checklists so the entire team follows the new procedure. Avoid claiming compliance without evidence of documentation or team communication.

Describe a time you found a non-obvious defect during inspection and what you did

Explain your inspection mindset that looks beyond obvious wear and follows inspection intervals, borescope checks, and system functional tests to catch subtle failures. Emphasize methodical checks and cross-referencing maintenance records to spot trends that point to hidden defects. Cite a specific case where you found hairline cracking in a control rod during a non-routine inspection, describing the tools you used to detect it and how you documented the finding and recommended inspection intervals fleet-wide. Explain how the repair prevented a larger failure and how you coordinated with engineering for a permanent fix. Point out that documenting and communicating findings prevents repeat occurrences across the fleet, and recommend follow-up inspections when appropriate. Avoid downplaying small defects because they can become critical over time.

How do you handle disagreements about whether an aircraft is fit to return to service

Describe a calm, evidence-based approach where you cite the maintenance manual, regulations, and inspection data to support your position, and involve quality assurance or the certifying inspector when opinions differ. Emphasize communication with operations and presenting clear options, including risk assessments and possible deferred-item procedures if allowed. Share an example where you disagreed with a pressure to sign off a repair prematurely, explaining how you requested additional tests, documented the discrepancy, and worked with the QA inspector to reach a resolution that protected safety without unnecessary delay. Show how you remained professional while insisting on required checks. Explain that safety and regulatory compliance override schedule pressure, and that escalation to the appropriate authority is the correct path when consensus cannot be reached. Avoid confrontational behavior and focus on facts and documented standards.

Tell me about a time you caught a safety issue that others missed

Situation: During a routine inspection prior to a ferry flight, I noticed an inconsistency in the hydraulic fluid level compared with recent entries in the logbook. Task: I needed to determine whether the discrepancy indicated a leak that could endanger flight safety or a documentation error. Action: I performed a focused inspection of hydraulic lines, fittings, and reservoirs, used dye checks where applicable, and coordinated a system pressure test with the avionics and hydraulic specialists. I documented findings, grounded the aircraft until we traced a minor leak at a fitting, and supervised the corrective repair and retest. Result: The aircraft was repaired and returned to service with a clear logbook entry, preventing a potential in-flight hydraulic failure and saving the operator from an incident. The operator updated their pre-flight checklist to include a quick reservoir cross-check after my report to reduce recurrence.

Describe a time you had to meet a tight turnaround without compromising quality

Situation: We had a short overnight window to complete a removal and replacement of an engine component that was critical for a morning departure. Task: My role was to coordinate the team to complete the repair, perform required tests, and maintain full documentation under time pressure. Action: I broke the job into parallel tasks, assigned experienced techs to critical steps, ensured tool and parts readiness, and kept an open line with the certifying inspector for immediate sign-off after testing. I also paused work when a torque reading was out of tolerance and rechecked procedures rather than rushing a fix. Result: We completed the repair, passed the functional checks, and released the aircraft on time without quality shortcuts, with zero safety issues reported. The process improved our turnaround planning and we added a pre-shift parts staging step to reduce future delays.

Give an example of mentoring a junior mechanic who was struggling with a task

Situation: A new hire was having difficulty following the correct torque and sequence for a control surface reinstallation, which caused rework and delays. Task: I needed to bring the trainee up to standard while keeping the backlog under control. Action: I scheduled a hands-on coaching session where I demonstrated the correct procedure, explained the why behind torque values and sequencing, and then supervised while the trainee repeated the task until proficient. I provided a written job aid and arranged a follow-up check after three similar tasks to confirm competence. Result: The trainee reached the required competency level and reduced rework by half in the next month, improving team efficiency. The written job aid became part of our onboarding packet for future hires.
