## Discrepancy

UPON DEPARTURE AFTER FLAP RETRACTION AT ABOUT 1000' NOTICED A STRONG BURNING SMELL IN COCKPIT AREA. DID NOT SEE SMOKE, LOOKED BACK IN CABIN AREA AND ALSO DID NOT SEE SMOKE, DID NOT GET ANY CAS MESSAGES NOR AUDIO WARNINGS , JUST A STRONG BURNING ODOR THAT STAYED UNTIL AFTER LANDING , AT WHICH TIME THE ODOR DIMINISHED BUT DID NOT ENTIRELY DISSIPATE.  RESEARCHED PREVIOUS MAINTENANCE DONE AND THE MM DOES NOT CALL OUT FOR 'AIR DUCT BURN IN'. LOOKED UP NJA COMPLY 365 AND FOUND TC-68A-21-181006MR3 ENVIRON CONTROL SYS BLEED AIR DUCT BURN OUT. ACCOMPLISHED TC-68A-21-181006MR3 ENVIRON CONTROL SYS BLEED AIR DUCT BURN PROCEDURE. REMOVED HEPA FILTER & INSTALLED NEW UNIT  IAW M/M 21-70-10. OPS CHKD GOOD.
