Split Airport incident highlights concerns over Airbus A220 engine reliability

An incident at Split Airport involving an Airbus A220-300 has once again cast a shadow over the reliability of the Pratt & Whitney GTF engines, which power not only this aircraft but also the entire new fleet of Croatia Airlines. While the crew's swift action in aborting takeoff before reaching critical speed V1 averted a potential disaster, the event has amplified existing concerns among aviation experts and operators worldwide.

Preliminary analyses suggest a possible temporary loss of power in the left engine during the takeoff roll, causing the aircraft to veer sharply left. The A220 is lauded for its modernity, fuel efficiency, and passenger comfort, but its exclusive reliance on Pratt & Whitney's GTF engines presents a single point of failure. Unlike the Airbus A320neo family, which offers a choice between Pratt & Whitney and CFM LEAP engines, the A220's lack of alternative engine options makes operators like Croatia Airlines particularly vulnerable.

These sophisticated GTF engines, despite their advanced technology, have been plagued by issues in recent years. Reports of frequent technical problems, premature engine removals, extended maintenance periods, and a shortage of spare parts have become common. The complexity of the geared turbofan system, while enabling efficiency, has also proven challenging to maintain. This has led to significant operational disruptions for airlines globally, with fleets being grounded and flights canceled. For Croatia Airlines, which has fully committed to the A220, this situation poses a considerable operational risk, especially during peak tourist season when every minute of aircraft downtime translates to substantial financial losses. The Split incident, while perhaps not directly linked to a design flaw, underscores the broader pattern of technical challenges associated with GTF technology.
