Typical Oral Questions

  1. What must the mechanic furnish the owner or operator of an aircraft if the aircraft he is giving a 100-hour inspection to proves to be unairworthy?

    A signed and dated list of all of the discrepancies that keep the aircraft from being airworthy.

  2. Where can you find the recommended statement to use for recording the approval or disapproval of an aircraft for return to service after a 100-hour inspection?

    In 14 CFR §43.11.

  3. Under what conditions can an aircraft be operated with a 100-hour inspection overdue?

    The aircraft can be operated for no more than 10 hours after an inspection is due for the purpose of flying it to a place where the inspection can be performed.

  4. For how long can an aircraft be operated if a 100-hour inspection is overdue?

    For no more than 10 hours. This time beyond the 100 hours allowed must be subtracted from the time before the next inspection is due.

  5. Under what conditions can an aircraft that is due an annual inspection be operated?

    It can only be flown when a special flight permit is issued.

  6. What certification is required for a mechanic to be able to approve an aircraft for return to service after a 100-hour inspection?

    A mechanic certificate with Airframe and Power-plant ratings.

  7. What determines whether or not an aircraft must be given a 100-hour inspection?

    Aircraft that carry persons for hire and aircraft that are used for flight instruction for hire must be given 100-hour inspections.

  8. What is the difference between an annual inspection and a 100-hour inspection?

    The inspections themselves are identical. An annual inspection can be performed only by an A&P mechanic who holds an Inspection Authorization, while a 100-hour inspection can be performed by an A&P mechanic without an IA.

  9. What certification is required for a mechanic to conduct an annual inspection and approve the aircraft for return to service after the inspection?

    In 14 CFR Part 43, Appendix E.

  13. Where can you find the requirements for inspecting the ATC transponder that is installed in an aircraft?

    In 14 CFR Part 43, Appendix F.

Typical Practical Projects

  1. Determine from the aircraft records furnished by the examiner whether or not any repetitive Airworthiness Directives must be complied with on a 100-hour inspection.
  2. Using the aircraft model and serial number specified by the examiner, determine what Airworthiness Directives apply to the aircraft. Examine the aircraft maintenance records to determine if all of the applicable ADs have been complied with.
  3. Determine from the aircraft records furnished by the examiner when the next 100-hour inspection is due and when the next annual inspection is due.
  4. Prepare an aircraft for a 100-hour inspection. Perform the inspection. Make the correct maintenance record entries to show that the inspection has been conducted.
  5. Describe to the examiner the record entry that must be made when an altimeter system has been inspected in accordance with 14 CFR §91.171.
