MAINTENANCE MANUAL STEMME S12
5.3.4 SPECIAL CONDITIONS AND CAUTIONARY NOTICE
Airplanes operated with high take-o/landing frequency or engaged in ight school use will likely
need more frequent inspections.
In addition, more frequent inspections and maintenance will be indicated for:
• Airplanes that are either stored or operated under other conditions than normal,
• Airplanes stored or operated in hot or humid tropical conditions,
• Airplanes stored or operated in cold or damp climates, and
• Airplanes stored or operated in extreme temperature or in arid conditions, etc.
The more frequent inspections should cover, at a minimum, wear, leaks, corrosion, delamination,
rubber deterioration, inexibility, loose connections, and lack of lubricant, hydraulic uid or cool-
ant. Under the special conditions described above, the owner and operator and his authorized
maintenance person should perform periodic inspections at a more frequent rate, i.e. at shorter
intervals, until they can set their own more frequent inspection periods based upon experience.
5.3.5 GENERAL REMARKS ON MAINTENANCE
The recommended periods for maintenance and for inspection do not constitute a guarantee or
warranty that the item will reach the recommended TBO without malfunction, as the range of
in-service factors cannot be controlled by the manufacturer.
It is always and ultimately the responsibility of the owner, the operator and the authorized main-
tenance organization to make well informed decisions when and whether to shorten the compo-
nents recommended TBO or TBR.
“On Condition” items are to be repaired, overhauled, rebuilt, or replaced using only manufactur-
er–specied parts or manufacturer–approved material and parts as appropriate, when inspection
or observed performance of these items reasonably reveals a potentially unserviceable or unsafe
condition.
The date on the applicable initial Certicate of Airworthiness issued with nal production
inspection is to be used as the starting date for all inspected components listed in chapters 4
and 5 of this aircraft’s Maintenance Manual. (Statement of Conformity, EASA Form 52).
