AvSafe worked with the defense team for Captain Richard Ashby, USMC and Captain Joseph Schweitzer, USMC in an effort to reconstruct the mishap which occurred on February 3, 1998 in Cavalese, Italy. Our role as the reconstructionist is to gather ALL the facts related to the mishap in an effort to find the cause or causes. In doing so we have visited the mishap site, interviewed witnesses, examined the mishap aircraft, reviewed mission recorder information, along with countless other tasks. We have also identified other experts in essential fields and coordinated the efforts of the expert team.
"TPC" or Tactical Pilotage Charts as depicted
in the adjacent photo are used by aircrew throughout the world both for
navigation, terrain and obstacle avoidance. These DOD supplied charts
are produced by NIMA (National Imaging and Mapping Agency) with source
information provided by the various countries-- such as Italy, in this
case. Even though information pertaining to the gondola was supplied to
NIMA by the Italian government, the gondola was never depicted on the
TPC chart used by the aircrew. In spite of the notable absence of any
aerial cable marking, the Marine Corps insisted on stating the cable
was marked on the chart. You can see for yourself that it clearly is
not marked. Today, the edition of this chart remains devoid of any
aerial cable marking for the gondola system in Cavalese although the
Austrian region to the north of the mishap valley is replete with
marked aerial cables.
The EA-6B Prowler struck the gondola support
cable (2 inch diameter) and haulage cable (1 inch diameter)with its
right wing at the wing fold. Post flight investigation revealed a
strike of approximately 40-50 degrees relative to the cable. Damage to
the Prowler was severe with both cables cutting the wing to the spar.
Also damaged were the ALQ99 jammer pod carried on wing station five and
the "football" or antenna fairing on top of the vertical stabilator.
On
May 11, 1996 ValuJet Flight 592, a DC-9, caught fire and crashed into
the Florida Everglades near Miami, Florida. All 105 passengers, and
five flight crew members perished. Initial efforts to recover the
aircraft wreckage were hampered by the swampy terrain. A specially
adapted pontoon type vehicle designed to operate in the Everglades
environment was used to assist in hauling heavy wreckage. A barge with
a backhoe bucket is shown here working the main crater.
Airboats
were used to transport personnel working in the swamp and to haul
smaller pieces to the decontamination stations. A surveyed grid search
was conducted with volunteers poking through the saw grass mat looking
for wreckage. Personnel were suited up in Tyvek suits, double rubber
gloved, hip waders and surgical masks while working in 90 degree heat
and humidity. Most wreckage was recovered in this manner.
Investigation
revealed that chemical oxygen generators (shown here) were responsible
for the fire in the forward cargo compartment of the DC-9. The fire
penetrated the passenger compartment above the cargo compartment.
Wreckage
was transported to Tamiami Airport for layout. The forward cargo hold
(shown here) was reconstructed using framing, chicken wire, and
recovered airframe wreckage. The layout revealed the most intense
portion of the fire was on the forward left side of the compartment.
