SECTION INSPECTION (Basic)

  •  WHICH PARTS ARE INVOLVED?
  • A hot section inspection (HSI) involves examining the condition of the turbine blades, the combustion chamber, the stators, the vane rings, the compressor turbine disk and the shroud segments.
  • WHEN SHOULD YOU DO IT?
  • required when the engine reaches the halfway point of its the time between overhauls If the 4,000 hours, an HSI should be scheduled at 2,000 hours of operation.
  •  known as a ‘hard-time HSI. specified in its maintenance manual.
  • While an HSI is usually done as a preventive, planned maintenance activity, unscheduled inspections are sometimes needed.
  •  if the battery is not in good condition when the engine starts up, it can result in an overtemp’ (high ITT) situation, warranting an unscheduled HIS.
  • Any certified technician can do an HSI. who has taken a course from P&WC and received approval from the local aviation authority, such as Transport Canada or the FAA in the United States.
  • WHY IS IT REQUIRED?
  • It helps make sure that the aircraft engine will continue delivering the expected power and performance. It will increase the engine’s durability.
  •  And it can reduce maintenance costs by providing operators with more control over their maintenance activities.
