Narrative:

A little over a month ago I was assigned a periodic service check on a B757 aircraft, nose number, I believe was xyz, upon accomplishing the check I found the #2 engine spinner (spin wxwx) fairing (yxyx) cracked at the mounting bolt area, the plane was OTS for about two days and engineering requested the defected part be tagged and ship to them. On mar/fri/00 I was assigned a periodic service check on a B757 aircraft, nose number XXX, upon accomplishing the check, I found both #1 and #2 engines spinner fairings (yxyx) cracked, engineering requested both fairings tagged and sent to them. The aircraft went OTS the same day and went back into service mar/tue/00. My purpose for this disclosure is based on my concern as listed: 1) the safety of the flying public, 2) the continuation of improvement of safety in global civil aviation, and 3) the welfare of the company's interest in all aspect regarding aviation maintenance and safety. When xyz went back into service (apr/fri/00) I believe its total time was a little under 5000 hours, that would make it a fairly new aircraft (XXX also appeared to be fairly new). I was expecting some form of action, such as maintenance service of spinner fairings on all related acfts with these particular engines/spinners assemblies, etc. I did not see or hear of any such actions. I am not familiar with the policies and procedures of the company and the FAA regarding these kind of events, however, I am concerned about the airworthiness of these fairings. Callback conversation with the reporter revealed the following information: the reporter stated when the cracked fairings were removed and sent to engineering, some action or information was expected, but nothing was heard from engineering. The reporter said the engines were rolls-royce RB211-535e4.

Narrative: A LITTLE OVER A MONTH AGO I WAS ASSIGNED A PERIODIC SERVICE CHK ON A B757 ACFT, NOSE NUMBER, I BELIEVE WAS XYZ, UPON ACCOMPLISHING THE CHK I FOUND THE #2 ENG SPINNER (SPIN WXWX) FAIRING (YXYX) CRACKED AT THE MOUNTING BOLT AREA, THE PLANE WAS OTS FOR ABOUT TWO DAYS AND ENGINEERING REQUESTED THE DEFECTED PART BE TAGGED AND SHIP TO THEM. ON MAR/FRI/00 I WAS ASSIGNED A PERIODIC SERVICE CHK ON A B757 ACFT, NOSE NUMBER XXX, UPON ACCOMPLISHING THE CHK, I FOUND BOTH #1 AND #2 ENGINES SPINNER FAIRINGS (YXYX) CRACKED, ENGINEERING REQUESTED BOTH FAIRINGS TAGGED AND SENT TO THEM. THE ACFT WENT OTS THE SAME DAY AND WENT BACK INTO SERVICE MAR/TUE/00.

WHEN XYZ WENT BACK INTO SVC (APR/FRI/00) I BELIEVE ITS TOTAL TIME WAS A LITTLE UNDER 5000 HOURS, THAT WOULD MAKE IT A FAIRLY NEW ACFT (XXX ALSO APPEARED TO BE FAIRLY NEW). I WAS EXPECTING SOME FORM OF ACTION, SUCH AS MAINT SERVICE OF SPINNER FAIRINGS ON ALL RELATED ACFTS WITH THESE PARTICULAR ENGINES/SPINNERS ASSEMBLIES, ETC. I DID NOT SEE OR HEAR OF ANY SUCH ACTIONS. I AM NOT FAMILIAR WITH THE POLICIES AND PROCEDURES OF THE COMPANY AND THE FAA REGARDING THESE KIND OF EVENTS, HOWEVER, I AM CONCERNED ABOUT THE AIRWORTHINESS OF THESE FAIRINGS. CALLBACK CONVERSATION WITH THE RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED WHEN THE CRACKED FAIRINGS WERE REMOVED AND SENT TO ENGINEERING, SOME ACTION OR INFORMATION WAS EXPECTED, BUT NOTHING WAS HEARD FROM ENGINEERING. THE RPTR SAID THE ENGINES WERE ROLLS-ROYCE RB211-535E4.
