Narrative:
Normal runup VFR departure 13R (A9 intersection) from bfi. Vibration noted after liftoff. (Similar to wheel spin down--brakes did not correct). Requested left crosswind to downwind to return to land 13L. Tower offered 270R/90L turn or 90R/270 left turn return to land 31L. Because of close proximity of the 'sfc to 7000' TCA at sea to the 13R centerline extended, aircraft may have penetrated northeast corner at 4 NM, R350, sea. Maximum altitude attained during the 270-90 reversal was 750' AGL (770' MSL). Power was reduced at about 750' when a clearly safe return to the airfield was established. (Landing was normal as was rollout. Engine vibration was noted on a post-flight full power runup. As of this date, the cause has not been identified and the aircraft has been deemed unairworthy.)

Title: POSSIBLE TCA PENETRATION WHEN ACFT MAKES 90-270 REVERSAL FOR IMMEDIATE LNDG OPPOSITE DIRECTION ACCOUNT ROUGH ENGINE.
Narrative: NORMAL RUNUP VFR DEP 13R (A9 INTXN) FROM BFI. VIBRATION NOTED AFTER LIFTOFF. (SIMILAR TO WHEEL SPIN DOWN--BRAKES DID NOT CORRECT). REQUESTED LEFT XWIND TO DOWNWIND TO RETURN TO LAND 13L. TWR OFFERED 270R/90L TURN OR 90R/270 L TURN RETURN TO LAND 31L. BECAUSE OF CLOSE PROX OF THE 'SFC TO 7000' TCA AT SEA TO THE 13R CENTERLINE EXTENDED, ACFT MAY HAVE PENETRATED NE CORNER AT 4 NM, R350, SEA. MAX ALT ATTAINED DURING THE 270-90 REVERSAL WAS 750' AGL (770' MSL). PWR WAS REDUCED AT ABOUT 750' WHEN A CLEARLY SAFE RETURN TO THE AIRFIELD WAS ESTABLISHED. (LNDG WAS NORMAL AS WAS ROLLOUT. ENG VIBRATION WAS NOTED ON A POST-FLT FULL PWR RUNUP. AS OF THIS DATE, THE CAUSE HAS NOT BEEN IDENTIFIED AND THE ACFT HAS BEEN DEEMED UNAIRWORTHY.)
