() ________________________________ Message 1 _____________________________________ Time: 05:38:50 AM PST US From: Subject: Avionics-List: Transponder Re-Check? 8/30/2009 Don Wrote "Will I need another transponder/encoder cert IAW 91.413?" Here is what 91.413 says: "91.413 ATC transponder tests and inspections. (a) No persons may use an ATC transponder that is specified in 91.215(a), 121.345(c), or 135.143(c) of this chapter unless, within the preceding 24 calendar months, the ATC transponder has been tested and inspected and found to comply with appendix F of part 43 of this chapter; and (b) Following any installation or maintenance on an ATC transponder where data correspondence error could be introduced, the integrated system has been tested, inspected, and found to comply with paragraph (c), appendix E, of part 43 of this chapter." It would appear that if you could satisfy yourself in some manner (preferably documented) that "data correspondence error" could not be introduced either by the repair or your subsequent reinstallation then no Appendix E recheck would be required. First flights after reinstallation should include some airborne check of the system with ATC. Why not ask the people who just did your check what their opinion is -- realizing that it may not be entirely unbiased.

I just had my biennial transponder/encoder certification (IAW FAR 91.413) done. The system passed and log book was signed off. On the very next flight, the transponder acted up. I had it pulled and sent off for repairs and it is due back Monday with a fresh 8130. Will I need another transponder/encoder cert IAW 91.413?
