Non- destructive Testing Applications in Commercial Aircraft Maintenance.

INTRODUCTION In aircraft maintenance programme it
is important to inspect the mechanical
damage and assess the extent of the
repair work. But in schedule
maintenance it is a difficult to finding
the defects rapidly, as the maintenance of aircraft must be accomplished
within scheduled time and same to be
released in time for commercial
operation. During aircraft maintenance
'NONDESTRUCTWE TESTING' (NDT) is the
most economical way of performing
inspection and this is the only way of
discovering defects. In simply we can
say, NDT can detect cracks or any other irregularities in the airframe
structure and engine components
which are obviously not visible to the
naked eye. Structures & different assemblies of
aircraft are made from various
materials, such as aluminium alloy,
steel, titanium and composite
materials. To dismantle the aircraft in
pieces and then examine each component would take a long time, so
the NDT method and equipment
selection must be fast and effective. In the present trend of NDT application
on aircraft 70-80% of NDT is
performed on the airframe, structure,
landing gears and the rest carried out
on engine & related components.

Types Of Flaps


Flaps are the most common high-lift devices used on aircraft. These surfaces, which are attached to the trailing edge of the wing, increase both lift and induced drag for any given AOA. Flaps allow a compromise between high cruising speed and low landing speed, because they may be extended when needed, and retracted
into the wing’ s structure when not needed. There are four common types of flaps: plain, split, slotted, and Fowler flaps.

FLYING BULLS TO DEBUT AT AERO INDIA

The Flying Bulls' aerobatics team, whose breathtaking displays are a
regular feature at various aviation and
motor sport events across the world,
will make its debut at this year ' s Aero India. The event to be held at the Air Force
Station Yelahanka, between February
9 and February 13, will witness the
Flying Bulls team performing on all five
days. Among the stunts which the four-
member Czech Republic-based team
will perform during the air show,
include the signature mirror flight
manoeuvre. While performing this manoeuvre, the
leading aircraft flies upside down,
immediately above a second aircraft
flying right side up, mirroring the
leading aircraft' s flight figures. The team, led by a woman pilot
Radoslava currently flies four Zlin 50LX
aircraft.
