Airworthiness Directives
The Federal Aviation Administration (FAA) publishes Airworthiness
Directives (AD’s) that apply to specific aircraft and aircraft appliances
or accessories. AD’s are mandatory changes and must be complied
with within a time limit set forth in the AD. Operators should
periodically check with Cirrus Service Centers or A&P mechanic to
verify receipt of the latest issued AD for their airplane.
Airplane Inspection Periods
• Note •
FAR 1.1 defines time in service, with respect to maintenance
time records, as “the time from the moment an aircraft leaves
the surface of the earth until it touches it at the next point of
landing.”
Serials 1633, 1639 and subsequent: The #2 Hour Meter,
located in the center console and labeled FLIGHT, begins
recording when the airplane reaches approximately 35 KIAS
and should be used to track maintenance time intervals as it
more accurately records time in service than the #1 Hour
Meter which begins recording when the BAT 1 switch is ON
and either the ALT 1 or ALT 2 switch is ON.
The inspection items specified in the Annual/100 Inspection
have been determined by the average aircraft use rate of the
typical owner. Non-commercially operated aircraft that are
flown significantly more than 100 hours per year should
consider additional inspections commensurate with the hours
flown. 100-Hour Inspection or enrollment in a Progressive
Inspection Program should be considered in addition to the
normally required Annual Inspection. The Annual Inspection
interval may also be shortened to accommodate high
utilization rate.
Annual Inspection
Unless enrolled in a Progressive Inspection Program, The U.S.
Federal Aviation Regulations require all civil aircraft must undergo a
thorough Annual Inspection each twelve calendar months. Annual
Inspections are due on the last day of the twelfth month following the
March 2010
