How to keep an aircraft airworthy always
Any mechanical vehicles including aircraft need periodic
inspections in order to keep them airworthy and safe. Aircraft repair and maintenance are of two types, one that is
pre-scheduled which happen due to normal wear and tear of the parts of the
aircraft. The other one is unscheduled Aircraft Repair which is usually unpredictable and problematic.
Procuring spares for aircraft
for scheduled maintenance is an easier thing. Any sane aviation services
keep a list of Spares For Aircraft in
their inventory at all times which have a tendency to break down easily.
Understanding these two types of maintenance is important for the aircraft owners as well as for
the pilots.
The scheduled repair
are preventative measures performed at regular intervals. They generally
include the 100-hour inspections, progressive inspections and annual
inspections. They also include the pre-flight checks done by the pilots to make
sure that the aircraft is ready to be flown and safe to be handled.
Aircraft
Repair and Spares for Aircraft:
The pre-flight checks include a check to see no obvious defects or
malfunctioning of any part of the aircraft against a checklist. It basically
involves the pilot to walk around the aircraft while inspecting the major
components like fuselage and other control surfaces for any wear and tear or
defects that can impede the safety of the aircraft.
It also includes a check of the cabin area, the cockpit, avionics
and the battery for proper functioning. In case this pre-flight check produces
some abnormality, the maintenance crew are contacted for this.
The annual inspection and 100-hour inspections are done annually and
after 100 hours of operation time respectively and are a more detailed check of
all systems. The progressive inspections, however, are typically used when the
aircraft cannot spend a lot of time in the hangar due to its flight schedule.
This is more of a spot examination of certain components of the aircraft in the
least possible amount of time.
However, the unscheduled maintenance can occur anytime when a
component malfunction or is suspected to malfunction. Many times they are born
out of the pre-flight check described earlier in terms of a worn-out tire,
sheared vacuum pump, rough running engine, etc. Any such occurrences require
the maintenance crew to perform the aircraft
repair before deeming it airworthy.
