SUMMARY This summary is for information only and is not approved for modification of the aircraft.
A. MODIFICATIONS CONF 001
MODIFICATION CLASSIFICATION MAJOR None MINOR None NOTE: As per EASA IR 21, a minor change is one that has no appreciable effect on the mass, balance, structural strength, reliability, operational characteristics affecting the airworthiness of the product. All other changes are major changes.

MODIFICATION CLASSIFICATION MAJOR None MINOR None NOTE: As per EASA IR 21, a minor change is one that has no appreciable effect on the mass, balance, structural strength, reliability, operational characteristics affecting the airworthiness of the product. All other changes are major changes.
CONF ALL B. REASON
(1) History A fuel pump removed from an aircraft due to an independent failure was returned to the vendor where cavitation erosion was observed to have breached the pump housing through the inlet webs and exposed the fuel pump power supply wires.
Although the evaluation of previously removed fuel pumps showed that some of these had also experienced similar erosion in varying degrees, no other instance of breakthrough was identified.
Due to design similarities, Part Number (PN) 568-1-28300-101, PN 568-1-28300-103, and PN 568-1-28300-200 only were considered affected.
(2) Objective/Action This Service Bulletin details the instruction to inspect:
