High_tension Magneto

               Aircraft high-tension magneto is a self-contained unit delivers high voltage to Spark plug, incorporating a coil, points and distributor. Coil having primary and secondary winding, step up the voltage to a spark-generating level, turn it into timed high tension electrical pulses, and sends it to the appropriate spark plug               Magnetos are fixed with manufacturer’s data plate  with either ‘L’ or ‘R’. The L or R does not refer to the position on the engine, but to the magnetos direction of rotation. In one instance, a left-hand rotation magneto was installed in the position where a right-hand rotation was specified. The result was a rough running engine with reduced power and the associated possibility of destructive detonation.              It is important to install serviceable magnetos with the correct part, model and configuration details for the intended engine. The correct magneto configuration should be verified against the approved maintenance da

FAA AD 2017-16-11 Lycoming

                This  AD   2017-16-11   requires an inspection of connecting rods and replacement of affected connecting rod small end bushings.  AD was prompted by several reports of connecting rod failures resulting in uncontained engine failure and in-flight shutdowns (IFSDs).   AD applies to:            (1) All Lycoming Engines reciprocating engines listed in Table 1 of Lycoming Engines MSB No. 632B, dated August 4, 2017, and (2) all Lycoming Engines reciprocating engines that were overhauled or repaired using any replacement part listed in Table 2 of Lycoming MSB No. 632B, which was shipped from Lycoming Engines during the dates listed in Table 2 of Lycoming  MSB No. 632B.                Reason of this AD is reports of uncontained engine failures and IFSDs due to failed connecting rods on various models of Lycoming Engines reciprocating engines listed in Table 1 of Lycoming MSB No. 632B, that were overhauled or repaired using any replacement part listed in Table 2 of Lyc

Issuance of AMEL Cat.A

                       Another step for compliance of CAR 66, DGCA has now decided to issue CategoryA licence to eligible person. As per revised Rule 61 of Aircraft Rules 1937 the Category A licence has been made non-type rated.                      A large number of technical person holding BAMEL/BAMEEC in heavy Aeroplane (HA)  and Jet Engine (JE) are employed in various organization may be considered for issuance of Category A licence. To get Category A licence competent authority has decided some modality to be complied with.                        The existing CAR 147 type training organisation will be permitted to conduct Difference Training (difference in syllabus of CAR 66 Cat A licence and syllabus of exiting basic licence/Certificate.Syllabus of difference training will be approve by DGCA HQrs.

CRITICAL MAINTENANCE TASKS

 The procedure should ensure that the following maintenance tasks are reviewed to assess their impact on flight safety:            (1) tasks that may affect the control of the aircraft flight path and attitude , such as installation, rigging and adjustments of flight controls;            (2) aircraft stability control systems (autopilot, fuel transfer);            (3) tasks that may affect the propulsive force of the aircraft , including installation of aircraft engines, propellers and rotors; and            (4) overhaul, calibration or rigging of engines, propellers, transmissions and gearboxes.
