 (b) completion of an inspection involving the use of an NDT method which has been performed and certified by the holder of a valid appropriate NDT authority;
 (c) completion of a repair or modification that involved manual welding, including braze welding, that has been performed by the holder of a valid appropriate welding authority;
 (d) maintenance of components which are supplied as bench tested units, installed in aircraft — limited to inspection, replacement and adjustment of parts normally adjustable or replaceable in service where the subsequent operation may be proved without the use of test equipment additional to that normally used for functional tests on the aircraft;
 (e) maintenance involving the following is excluded unless the licence holder is, or is employed by, the holder of a valid appropriate certificate of approval:
 (i) separation and assembly of a reciprocating engine crankcase;
 (ii) disassembly or assembly of a crankshaft of a reciprocating engine — including removal and replacement of a connecting rod;

 (f) maintenance of electrical and instrument components which form part of an engine system limited to:
 (i) on all aircraft:
 (A) external mechanical adjustment to facilitate correct operation of engine systems; and
 (B) replacement of components connected by electrical plugs, terminal connections (other than soldered connections) or pipelines — but excluding those functional tests and adjustments requiring the use of external specialised test equipment; and
 (ii) on aircraft approved for I.F.R. operations;
