Narrative:
Departing runway 3 at foe, was given the following departure: after departure, turn right heading 180 degrees, climb to and maintain 8000 ft, contact departure on 123.8. While in the right turn to 180 degrees and climbing through 6000 ft, we encountered very light hail for approximately 2-3 seconds, followed by very heavy hail for approximately 8 seconds. WX radar was on in the aircraft with no indications of severe WX. During this time the aircraft sustained a cracked windshield and what appeared to be light to moderate droop/leading edge damage. The appropriate checklist was completed immediately and all limitations complied with. It was determined through dual concurrence of both crew members that flight could be continued in accordance with the checklist. This decision was based on the following: 1) the view from the cockpit indicated only light to moderate damage. 2) the engine instruments indicated no abnormalities. 3) all flight instruments were functioning properly and crosschecked. 4) the checklist advised continued flight within these limitations: a) airspeed below 230 KIAS. B) maximum differential pressure not to exceed 7.5. C) high windshield heat not to be used. 5) dual concurrence between both crew members that safe flight could be continued. Upon landing at elp, the aircraft was inspected and it was found to have sustained damage to the leading edge of wings and vertical stabilizer, radome damage (chipped pieces more than 60% of radome). Engine nacelle and bullet nose of compressor sections were dented (#1 engine greater than #2) as well as captain's windshield cracked (approximately 18 inches). WX was checked prior to departure. WX radar was used and there were no warnings/indications or hail in the area.

Title: FALCON 20 ON INITIAL CLB ON ASSIGNED HDG SUSTAINS SIGNIFICANT ACFT DAMAGE UPON ENCOUNTERING HAIL.
Narrative: DEPARTING RWY 3 AT FOE, WAS GIVEN THE FOLLOWING DEP: AFTER DEP, TURN R HDG 180 DEGS, CLB TO AND MAINTAIN 8000 FT, CONTACT DEP ON 123.8. WHILE IN THE R TURN TO 180 DEGS AND CLBING THROUGH 6000 FT, WE ENCOUNTERED VERY LIGHT HAIL FOR APPROX 2-3 SECONDS, FOLLOWED BY VERY HVY HAIL FOR APPROX 8 SECONDS. WX RADAR WAS ON IN THE ACFT WITH NO INDICATIONS OF SEVERE WX. DURING THIS TIME THE ACFT SUSTAINED A CRACKED WINDSHIELD AND WHAT APPEARED TO BE LIGHT TO MODERATE DROOP/LEADING EDGE DAMAGE. THE APPROPRIATE CHKLIST WAS COMPLETED IMMEDIATELY AND ALL LIMITATIONS COMPLIED WITH. IT WAS DETERMINED THROUGH DUAL CONCURRENCE OF BOTH CREW MEMBERS THAT FLT COULD BE CONTINUED IN ACCORDANCE WITH THE CHKLIST. THIS DECISION WAS BASED ON THE FOLLOWING: 1) THE VIEW FROM THE COCKPIT INDICATED ONLY LIGHT TO MODERATE DAMAGE. 2) THE ENG INSTS INDICATED NO ABNORMALITIES. 3) ALL FLT INSTS WERE FUNCTIONING PROPERLY AND XCHKED. 4) THE CHKLIST ADVISED CONTINUED FLT WITHIN THESE LIMITATIONS: A) AIRSPD BELOW 230 KIAS. B) MAX DIFFERENTIAL PRESSURE NOT TO EXCEED 7.5. C) HIGH WINDSHIELD HEAT NOT TO BE USED. 5) DUAL CONCURRENCE BTWN BOTH CREW MEMBERS THAT SAFE FLT COULD BE CONTINUED. UPON LNDG AT ELP, THE ACFT WAS INSPECTED AND IT WAS FOUND TO HAVE SUSTAINED DAMAGE TO THE LEADING EDGE OF WINGS AND VERT STABILIZER, RADOME DAMAGE (CHIPPED PIECES MORE THAN 60% OF RADOME). ENG NACELLE AND BULLET NOSE OF COMPRESSOR SECTIONS WERE DENTED (#1 ENG GREATER THAN #2) AS WELL AS CAPT'S WINDSHIELD CRACKED (APPROX 18 INCHES). WX WAS CHKED PRIOR TO DEP. WX RADAR WAS USED AND THERE WERE NO WARNINGS/INDICATIONS OR HAIL IN THE AREA.
