Carpatair ATR crash probe
highlights pilots' experience gap

LONDON
Investigators have
disclosed that a Carpatair ATR 72-500 captain breached operating
procedures while attempting an approach to Rome in strong gusting crosswinds,
before a bounced landing which badly damaged the aircraft.
It had been operating a service
to Rome
Fiumicino on behalf of Alitalia on 2 February 2013. The crew had
been informed of 22kt winds gusting to 37kt.
These gusts exceeded the
operating limits for the aircraft. But cockpit-voice recorder information shows
the crew did not carry out a landing briefing – during which the pilots would
normally have discussed the weather situation at the destination and alternate
airports.
The night-time approach to
runway 16L was flown at 130kt which, says investigation authority ANSV, was
“significantly” higher than the 118kt normally expected.
But ANSV points out that the
first officer – with less than 15h on type – was far less experienced than the
captain, who had over 9,600h on ATRs.
This huge difference probably
“inhibited” the first officer’s ability to speak out about the situation and
she accepted uncritically the airspeeds communicated by the captain, who was
flying.
ANSV says the captain had
“conviction” about his ability to land the aircraft safely, despite the weather
situation, and the pilots’ experience gap rendered crew-resource management
techniques “ineffective”.
The turboprop struck the runway
with 2.6° nose-down pitch, some 560m from the threshold, and bounced off its
nose-gear.
Its crew did not attempt a
go-around after the impact. ANSV says the pilots made opposite control inputs
after the bounce – the captain pushing down while the first officer pulled up –
which decoupled the flight controls.
The aircraft contacted the
runway a second time, badly damaging the nose-gear and interrupting the power
to the engines as a result of impact forces on the cockpit control levers.
ANSV says this second impact
compromised “any possibility of recovery” for the landing. The decoupling led
the aircraft to roll slightly left and it bounced off each main landing-gear,
damaging both. The aircraft subsequently slid on its fuselage underside for
some 400m and rotated nearly 180° as it veered off the runway and came to a
halt on grass.
None of the 50 occupants was
seriously injured. The investigators have cited “improper” operation of the
aircraft by the captain which was “not consistent” with the carrier’s
procedures in critical conditions.
