Aerolíneas Argentinas grounds eight 737-800s after repeated CFM56-7B engine failures

Aerolíneas Argentinas has grounded eight Boeing 737-800s after multiple failures of CFM56-7B engines, prompting pilot backlash and triggering an airline safety review. The move reduces the carrier's narrowbody availability, forces schedule adjustments and highlights operational risk tied to recurring in‑service engine problems.

Briefing

What Hype is tracking

The airline has grounded eight 737-800s after repeated CFM56-7B failures, removing immediate narrowbody capacity and forcing schedule changes; similar in‑flight engine failures have previously forced diversions (Southwest 737 diverted after engine failure).
Pilot backlash and the launch of a safety review mirror industry responses that lead operators and regulators to tighten inspections and procedures (US 747-400 operators intensified aileron inspections).
Recurring engine reliability issues increase maintenance and spares demand, a pressure that has driven airlines to cannibalise aircraft when parts are constrained (Aeroflot cannibalises eight Boeing freighters for spares).
