September 18 is the comment deadline for two separate notices of proposed rulemaking (NPRM). The comment period ends Monday on a proposal for transport aircraft manufacturers, including business jet OEMs, to establish operational limitations to prevent widespread fatigue damage for all future Part 25 designs. For existing designs, the requirement would apply only to jets with mtow of more than 75,000 pounds and operated under Part 121.
Maximum Takeoff Weight
At AOPA Expo yesterday Piper announced it had selected a variant of the Williams International FJ44-3A turbofan to power its new PiperJet. The Fadec-equipped FJ44-3AP will have a maximum thrust rating of 3,000 pounds but will be derated to 2,400 pounds for use in the new single-engine very light jet. Piper plans to fly the PiperJet in spring 2008 and start deliveries in 2010.
All jet and transport-category airplanes with an mtow of 12,500 pounds or more for which application of a new type design is submitted on or after Jan. 1, 2006, will have to meet new noise certification levels.
Raisbeck Engineering received approval of an mtow increase, to 10,350 pounds, for King Air C90s and C90Bs that have been modified with four-blade Hartzell/Raisbeck Quiet Turbofan Propellers. The modification also improves runway distance takeoff performance, according to the Seattle company. Besides the new propellers, Raisbeck’s $61,950 C90 performance-enhancing package includes dual aft body strakes and wing lockers.
Pilatus’ PC-12 turboprop single will receive several upgrades next year, raising the base price of the aircraft by $80,000 to $2.79 million and a typically equipped aircraft to $3.4 million. Mtow goes up to 10,450 pounds from 9,920 pounds for a 530-pound increase in useful load. New winglets will reduce drag and improve crosswind control, and Flettner tabs on the ailerons will reduce roll control forces, Pilatus said.
On September 20 Raytheon Aircraft received Part 23 commuter category certification of a King Air 350, a milestone in the company’s plan eventually to offer a Model 350ER, a special-missions version of the twin turboprop. This new aircraft has been modified with a heavyweight landing gear, as well as several airframe mods, permitting it to operate at an mtow of 16,500 pounds, an increase of 1,500 pounds over a standard 350.
A spokesman for the Port Authority of New York and New Jersey (PANYNJ) told AIN its chairman, Anthony Coscia, would use “whatever means necessary,” including legal action and “substantial” increases in landing fees, to achieve its agenda at Teterboro Airport (TEB).
Greer Aviation has opened security screening facilities at its FBOs in Edinburgh and Prestwick, Scotland. Equipped with metal detectors and baggage scanners, the facilities are designed to meet expected securityrequirements for commercial flights, including executive charter and fractional operations, in aircraft with mtow between 6,000 and 22,000 pounds.
All jet and transport-category airplanes for which application of a new type design is submitted on or after January 1 next year will have to meet Stage 4 noise certification levels. Stage 4 is a cumulative 10 EPNdB (effective perceived noise level in decibels) less than the current Stage 3 limits. All business jets currently manufactured meet Stage 3, and nearly all would qualify to be recertified to meet Stage 4.
On March 31 exemptions to ACAS II (TCAS II, Change 7) requirements in Europe were set to expire. The rule, which had been delayed by more than a year to give operators time to equip, covers all civil turbine-powered airplanes with mtow greater than 12,566 pounds or configured for more than 19 passengers.
