Embraer Praetor 600E Earns Simultaneous Certification from ANAC, EASA, and FAA on a Single Day
Embraer’s updated Praetor 600E supermidsize business jet received simultaneous type certification from Brazil’s National Civil Aviation Agency (ANAC), the European Union Aviation Safety Agency (EASA), and the U.S. Federal Aviation Administration on April 30 — a rare triple approval achieved on a single day. The certification covers structural and cabin upgrades over the baseline Praetor 600, which entered service in 2019. Changes include redesigned galleys, higher cabin ceilings, new seating, and an optional Smart Window display system. Embraer plans initial deliveries of both the 500E and 600E variants from 2029, with regulatory approval for the Praetor 500E expected by year-end.

Bombardier Q1 Profit Rises 20% as Engine Supply Shortfall From One Supplier Constrains First-Quarter Deliveries
Bombardier reported a $53 million operating profit in the first quarter of 2026 — up 20% year on year — while disclosing that deliveries fell short because of supply constraints from one of its three engine partners. CEO Eric Martel, speaking April 30 on the first-quarter earnings call, said shortfalls from a single engine provider continue to hurt “quite extensively.” Rolls-Royce, GE Aerospace, and Honeywell supply engines for the company’s current business jet portfolio. Bombardier maintained its full-year guidance of 157 jet deliveries and more than $10 billion in revenue, and its order book now exceeds $20 billion.

FAA Proposes Mandatory Corrosion Checks on 1,152 GE CF34-3 Engines Following Fatal Florida Challenger 604 Crash
The Federal Aviation Administration released a proposed airworthiness directive on April 30 requiring operators to complete start tests and high-pressure compressor case borescope inspections on GE Aerospace CF34-3 turbofans installed in 1,152 U.S.-registered aircraft. The rule follows a February 2024 fatal crash in which a Hop-A-Jet Bombardier Challenger 604 lost thrust in both engines on approach to Naples Municipal Airport in Florida and crashed on a highway, killing both pilots. The National Transportation Safety Board cited extensive corrosion in both engines’ variable-geometry stator vane systems as the cause. Some engines require inspection before the next flight; others within one to two years.

Airbus Targets End-of-June Delivery Recovery as Fuselage Panel Defects Cut Q1 Commercial Output by 22%
Airbus delivered 114 commercial aircraft in the first quarter of 2026 — down 22% from 136 in the same period last year — as repairs to forward fuselage panel thickness deviations on A320neo-family jets constrained output. CEO Guillaume Faury said corrective action requires “quite a bit of work” but that measures are “progressing well” and the issue will be “almost completely behind us” by the end of the first half. Airbus is aiming to resynchronise production and delivery schedules before the second half and maintains its full-year target of 870 commercial aircraft deliveries. Pratt & Whitney engine supply remains the other primary constraint on the A320neo ramp-up.

Rolls-Royce Q1 Trading Update Shows 5% Growth in Large Engine Hours as Middle East Trent XWB Activity Fully Recovers
Rolls-Royce reported that flight hours on its large civil engines grew 5% to 115% of 2019 levels in the first quarter of 2026, with CEO Tufan Erginbilgic telling shareholders at the April 30 annual general meeting that Trent XWB hours in the Middle East have “fully recovered” to pre-conflict levels. The company expects full-year large engine flying hours to exceed 2019 levels by 115% to 120%. Rolls-Royce also highlighted orders for eight Trent 1000 XE turbofans in the quarter, including three destined for LATAM Airlines. The XE variant features new long-life high-pressure turbine blades and a cooling system delivering 40% greater cooling flow than its predecessor.

MTU Aero Engines Reports Zero MRO Cancellations in Q1 as Commercial Overhaul Revenue Rises 8% to €1.6 Billion
MTU Aero Engines disclosed first-quarter 2026 results on April 30 showing no deterioration in aftermarket demand despite global trade uncertainty. CEO Johannes Bussmann stated on the earnings call that “in our shops, we have not received a single cancellation or meaningful deferral as of now.” Commercial MRO revenues rose 8% year on year to €1.6 billion ($1.9 billion), driven by sustained demand for overhauls of the Pratt & Whitney PW1000G geared turbofan, which accounted for 44% of commercial MRO revenue. MTU still holds a backlog of engines awaiting shop slots, providing a buffer against near-term demand softening.

Smartwings Issues Crew Guidance on Overspeed Recovery After Boeing 737-800 In-Flight Upset During High-Altitude Cruise
Czech aviation authority UZPLN has released its findings on a February 27 in-flight upset involving a Smartwings Boeing 737-800 on the Prague–Hurghada route at 37,000 feet in Greek airspace. Indicated airspeed climbed from Mach 0.77 to Mach 0.81 over 16 seconds, approaching the maximum operating limit. The crew reduced both engines to near-idle to arrest the acceleration, but the right-hand engine failed to respond when thrust was reapplied, triggering a minimum manoeuvring speed warning. No fault was identified; fuel filters were changed as a precaution and the aircraft returned to service. Smartwings has since directed crews to deploy speedbrakes rather than reduce thrust to idle when correcting an overspeed.
