3.0 Inspections
All S-LSA aircraft must undergo an annual condition inspection by a qualified Repairman with
at least a Maintenance rating (LSR-M). This requires satisfactory completion of an FAA
approved 104-hour Repairman-Maintenance class for Weight Shift Control. In addition,
anyone with an A&P certificate with Rotax Line Service Training may perform the
inspections.
For S-LSA aircraft used for non-commercial operation, an inspection is required every 12
months. For S-LSA aircraft used for commercial training or towing, an inspection is required
every 100 hours of operating time in addition to the annual condition inspection. The checklist
for these inspections is the same and is given below. This list incorporates all the applicable
items required by FAR 43, Appendix D.
The Annual or 100-Hour Inspection supplements the pre-flight inspection that should be done
prior to each flight. Since this inspection may be done by another person other than the owner
or pilot, the inspection list includes checks from the pre-flight list as well. If problems are
identified by the inspection that should have been identified by the pilot during pre-flight
checks, the pre-flight procedure should be modified to assure all points are being checked.
If the annual or 100-hour inspection is performed properly, there is no need for additional,
more in-depth inspections at longer intervals. All degradation mechanisms are covered in the
standard annual/100hour inspections.
3.1 Inspection Procedure
The following steps must be followed prior to performing the actual inspection to achieve an
effective inspection:
1.
Clean the aircraft. Prepare a discrepancy list by walking around the aircraft and noting
any visible damage or problems such as leaks and skin and sail damage. Examine any
questionable areas closely and identify problems before proceeding.
2.
After noting where leaks are visible, clean those areas with an appropriate solvent
3.
Start engine and do magneto check for each magneto. Note any problems for further
investigation.
4.
Run engine for at least five minutes after minimum oil temperature is achieved (120F)
and at a moderate load point (about 2500 rpm). On hot days, this may require fast
taxiing or flying to keep temperature from exceeding its limit of 285F.
5.
Note effectiveness of brake at holding trike during the 3500 rpm run-up. Also note
amount of pedal travel required to hold trike. If excessive, brake pads may need
replacement or hydraulic lines may need bleeding.
6.
Run engine at maximum RPM to check for proper propeller pitch. Acceleration should
be smooth and achieve maximum RPM in 3 seconds or less. Failure to reach an
indicated maximum speed between 5200 – 5500 RPM could be caused by excessive
