Narrative:
DURING INITIAL CLIMB AT 300 FEET AGL, THE UPPER COWL RAISED UP BETWEEN 1 AND 2 INCHES. THE PILOT REPORTED HE STAYED IN THE PATTERN. ON BASE LEG, THE UPPER COWL DISLODGED FURTHER FROM THE ACFT AND PRODUCED DRAG. UNABLE TO MAINTAIN ALTITUDE, A FORCED LANDING WAS MADE DURING WHICH THE ACFT COLLIDED WITH POWER LINES AND HOMES 1/2 MILE FROM THE RUNWAY. PRIOR TO THE FLIGHT, THE PILOT, WHO OWNED THE ACFT AND WHO WORKED AS AN A & P MECHANIC, HAD REMOVED AND PARTIALLY REPLACED THE ENGINE COWL. A FRIEND OF THE PILOT, WHO ALSO HELD AN A & P CERTIFICATE AND WAS A PILOT, ASSISTED BY PLACING THE LEFT SIDE OF THE UPPER COWL BACK ON THE ENGINE COMPARTMENT. THE SURVIVING PILOT REPORTED THAT HE HAD NOT OBSERVED THE PILOT-RATED PASSENGER PHYSICALLY SECURE THE LEFT SIDE OF THE UPPER COWL TO THE ENGINE COMPARTMENT. DURING THE WRECKAGE EXAM, ALL OF THE FIRE-DAMAGED COWL STRUCTURE WAS FOUND AT THE CRASH SITE EXCEPT FOR THE TWO FORWARD-POINTED UPPER COWL ENGAGEMENT PINS AND THEIR SUPPORTING STRUCTURE. ALSO NOT FOUND WAS THE NYLON GROMMET/BUSHING WHICH NORMALLY WAS SEATED IN THE LOWER COWL'S LEFT SIDE FORWARD PLATE ASSEMBLY. CAUSE: the failure of the upper engine compartment cowl to remain attached to the lower cowl during initial climb as a result of inadequate maintenance and replacement practices by the aircraft owner.
