Narrative:

Flew incorrect heading and altitude after IFR takeoff from bkl. Initial clearance was changed after I was on the runway in takeoff position. I held on the runway for at least 5-10 mins waiting for a revised clearance. After takeoff, I did not properly follow the new clearance. Problem could have been avoided had I been given a final clearance initially or, at least not after I was in takeoff position and holding for takeoff. The changes and stress induced by this contributed to the problem.

Title: PLT OF A BEECH BONANZA BE36 FAILED TO FOLLOW ASSIGNED DEP CLB HDG AND ALT AFTER TKOF DUE TO STRESS CAUSED BY LAST MIN CLRNC AMENDMENT JUST PRIOR TO THE TKOF ROLL.

Narrative: FLEW INCORRECT HDG AND ALT AFTER IFR TKOF FROM BKL. INITIAL CLRNC WAS CHANGED AFTER I WAS ON THE RWY IN TKOF POS. I HELD ON THE RWY FOR AT LEAST 5-10 MINS WAITING FOR A REVISED CLRNC. AFTER TKOF, I DID NOT PROPERLY FOLLOW THE NEW CLRNC. PROB COULD HAVE BEEN AVOIDED HAD I BEEN GIVEN A FINAL CLRNC INITIALLY OR, AT LEAST NOT AFTER I WAS IN TKOF POS AND HOLDING FOR TKOF. THE CHANGES AND STRESS INDUCED BY THIS CONTRIBUTED TO THE PROB.
