On 21 June 2022, a Boeing 737-9 cleared for a visual approach and landing on runway 28C at Pittsburgh landed on the adjacent runway 28L instead. The controller stated that having become aware that the aircraft was lined up with the wrong runway in the absence of any potential hazards, he had decided not to intervene. The crew said that a transient avionics fault on final approach had reduced their opportunity to ensure correct runway alignment but this fault was found to have cleared much earlier. It was noted that runway 28L had sequenced approach lighting whereas 28C had none.
