Borescope Inspection

Whats Included

  • Internal Cylinder Inspection - visual examination of cylinder walls, piston crowns, and combustion chambers to assess overall condition.

  • Exhaust valve condition assessment - Inspection of exhaust valves for signs of burning, asymmetry, hot spots, or abnormal wear patterns.

  • Intake valve Inspection - Evaluation of intake valves for deposits, seating condition, and airflow-related irregularities.

  • Cylinder wall evaluation - Identification of scoring, glazing, corrosion, or abnormal wear that could affect compression and engine performance.

  • Piston Crown Inspection - Detection of carbon buildup, detonation indicators, and uneven combustion patterns.

  • Combustion Chamber Analysis - Assessment of internal cleanliness, deposits, and signs of overheating or detonation.

  • Foreign Object Damage (FOD) check - Inspection for evidence of debris or damage inside the cylinder.

  • Trend-based condition awareness - Findings can be used to monitor changes over time and support proactive maintenance decisions.

  • Documentation Included - Every Borescope inspection includes clear photo and/or video documentation of key findings.

  • High resolution images of cylinder interiors

  • Visual evidence of any abnormalities or areas of concern

  • organized documentation for your maintenance records

  • Clear explanation of findings in plain, understandable terms

Why it Matters

A borescope inspection provides insight into your engines condition that cannot be obtained through external checks alone this allows for

  • Early detection of developing issues

  • more informed maintenance decisions

  • reduced risk of unexpected engine problems

  • Greater confidence in engine health and performance

Additional Considerations:

Applicable Airworthiness Directives and service bulletins may be reviewed in conjunction with Inspection findings

EVERY BORESCOPE INSPECTION IS PERFORMED WITH A FOCUS ON ACCURACY, CLARITY, AND REAL-WORLD ENGINE CONDITION-NO SHORTCUTS, NO GUESS WORK
