Aircraft Type: ATR 42-512
Owner/operator: Air Littoral
Registration Number: F-GPYE
Location: Florence-Peretola Airport (FLR) – ÿ Italy
Phase of Flight: Landing
Status: Destroyed, written off
Casualties: Fatalities: 1 / Occupants: 17
Component Affected: Aircraft Control Systems (specifically, the approach and landing phases)Aircraft Control Systems (specifically, the approach and landing phases)
Category: Accident
A flight from Nice-C“te d’Azur Airport (NCE) to Florence-Peretola Airport (FLR) experienced a significant incident involving an ATR 42-512 aircraft. The aircraft initiated a Circle-to-Land approach on runway 05, with the pilot flying in the left seat being a captain undergoing training. Following clearance, the instructor pilot and Not Flying pilot executed the approach, and the climbing and cruising phases were uneventful. During the approach, the Tower controller instructed the aircraft to land on runway 23, and the instructor captain authorized this. The pilots then proceeded downwind and prepared for a Circle-to-Land approach. The aircraft experienced a series of warnings, including GPWS ‘Sink Rate’ and ‘Pull up’ alerts, and subsequently crossed the threshold with a speed of approximately 145 kts. Due to a strong wind component, the aircraft crashed into the airport net-fencing, resulting in a complete stop and damage to the left engine. The incident was caused by an incompatibility between the planned Circle-to-Land approach and company safety standards, insufficient crew coordination, and the influence of a strong wind.A flight from Nice-C“te d’Azur Airport (NCE) to Florence-Peretola Airport (FLR) experienced a significant incident involving an ATR 42-512 aircraft.

Description

Air Littoral flight 701A, an ATR 42-512, suffered a runway excursion after a long and fast landing on runway 23 at Florence-Peretola Airport (FLR), Italy. The aircraft took off from Nice-C“te d’Azur Airport (NCE), France, on a flight to FLR. The Pilot Flying in the left seat was a captain undergoing training. The instructor pilot and Pilot Not Flying was seated on the right. The climbing and cruising phases were uneventful. During the approach, the Tower controller cleared the flight to land on runway 05. The instructor captain then requested an approach to runway 23 for training purposes. This was authorized by the Tower controller. The pilots then proceeded downwind and prepared for a Circle-to-Land approach. They were keeping an altitude of 2500 feet until the base leg. During the base turn, the PNF selected the flaps to 35ø and urged the PF the push the nose down. In the descending turn the GPWS sounded multiple times with ‘Sink Rate’ and ‘Pull up’ warnings. The aircraft then crossed the threshold with an indicated speed of about 145 kts. The aircraft touched down for the first time about 450 m from the touchdown zone and bounced twice. At a speed of about 104 kts and at less than 350 m from the end of the available runway, the aircraft put its wheels firmly on the runway. Braking was applied immediately, The aircraft continued across the grassy terrain until it crashed into the airport net-fencing at the edge of the A11 motorway, and the aircraft came to a complete standstill, with the left engine still running. CAUSES The crew planned and carried out the MVL (Circle-to-Land) approach which took the aircraft to an approach flight path incompatible with respect to the safety parameters set down by the company standards. Despite the activation of the alarm systems, the expected go-around manoeuvre was not started also because of an insufficient crew coordination between the two flight crew members. The presence of a significant wind component from the north cannot be completely excluded, which further destabilized the spatial flight path of the aircraft.
