## Probable cause

A POWER LOSS OF UNDETERMINED ORIGIN. FACTORS RELATED TO THE ACCIDENT WERE THE NIGHT CONDITIONS, THE LACK OF A SUITABLE LANDING AREA, AND THE INABILITY OF THE PILOT TO MAINTAIN ROTOR RPM WHILE MANEUVERING TO AVOID OBSTACLES.

## Sequence of events

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

- Loss of engine power, climb - to cruise
  - reason for occurrence undetermined (cause)
- Forced landing, descent - emergency
  - autorotation - performed, pilot in command
- Hard landing, landing
  - light condition - night (contributing factor)
  - terrain condition - none suitable (contributing factor)
  - terrain condition - high obstruction(s)
  - adequate rotor rpm - not maintained, pilot in command (contributing factor)

## Analysis

THE BALTIMORE POLICE DEPTARTMENT PILOT WAS SUPPORTING UNITS ON THE GROUND, AND AFTER COMPLETING AN ASSIGNMENT, HE STARTED A CLIMB.  DURING A CLIMB THROUGH APPROXIMATELY 200 FEET AGL, A LOSS OF ENGINE POWER OCCURRED OVER A HIGH DENSITY RESIDENTIAL AREA.  WHILE MANEUVERING TO AVOID OBSTACLES DURING AN AUTOROTATION, HE LOST ROTOR RPM AND MADE A HARD LANDING IN A STREET INTERSECTION.  THE ENGINE WAS TEST RUN SATISFACTORILY AND THE CAUSE OF THE POWER LOSS WAS NOT DETERMINED.
