## Probable cause

FAILURE OF THE ALTERNATOR AND THE PILOT'S INADVERTENT DESCENT.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Airframe/component/system failure/malfunction, takeoff - initial climb
  - electrical system,alternator - inoperative (cause)
  - electrical system - failure,total
- In flight collision with terrain/water, approach
  - light condition - dark night
  - descent - inadvertent, pilot in command (cause)

## Analysis

THE PILOT DEPARTED AFTER MIDNIGHT ON THE LAST LEG OF A BUSINESS TRIP.  HE REPORTED HE LOST ELECTRICAL POWER AFTER GEAR RETRACTION DURING CLIMB FROM TAKEOFF.  HE USED A FLASHLIGHT FOR COCKPIT ILLUMINATION AND A MOBILE TELEPHONE TO CONTACT SOMEONE AT THE DESTINATION.  NEARING THE DESTINATION, HE EXTENDED THE LANDING GEAR MANUALLY, DESCENDED TO PASS OVER THE FIELD FOR A VISUAL CHECK OF THE GEAR, AND CONTINUED TROUBLESHOOTING. THE AIRPLANE COLLIDED WITH THE GROUND 2.5 MILES NORTH OF THE FIELD.  TWO CONNECTIONS FOR THE ALTERNATOR WERE FOUND LOOSE OR BROKEN.
