Narrative:
Shortly after takeoff lost all power. Radio as well. Restored power, then discovered directional gyroscope off by 45 degrees. This was also noticed by departure. Corrected heading by magnetic compass to follow departure's vectors. Able to get directional gyroscope aligned and back on in 3-4 mins. Advised departure of this. Rest of flight uneventful. Cause: weak circuit breaker. Mechanical correction done.

Title: TEMPORARY LOSS OF RADIO CONTACT AND HDG TRACK DEV DURING A PRIMARY ELECTRICAL PWR SUPPLY PROBLEM INTERRUPTION.
Narrative: SHORTLY AFTER TKOF LOST ALL PWR. RADIO AS WELL. RESTORED PWR, THEN DISCOVERED DIRECTIONAL GYROSCOPE OFF BY 45 DEGS. THIS WAS ALSO NOTICED BY DEP. CORRECTED HDG BY MAGNETIC COMPASS TO FOLLOW DEP'S VECTORS. ABLE TO GET DIRECTIONAL GYROSCOPE ALIGNED AND BACK ON IN 3-4 MINS. ADVISED DEP OF THIS. REST OF FLT UNEVENTFUL. CAUSE: WEAK CIRCUIT BREAKER. MECHANICAL CORRECTION DONE.
