Gross Weight Increase to 9,187 lbs on Wipline 8750 floats

Wipaire, Inc. has received Federal Aviation Administration (FAA) approval to increase the Cessna Grand Caravan’s gross weight to 9,187 lbs. (4,167 kg) on Wipline 8750 floats. The Supplemental Type Certificate (STC) adds 125 lbs. (56 kg) of useful load and is available for floated aircraft equipped with the PT6A-140 engine. Eligible aircraft include production Grand Caravan EX aircraft and Grand Caravans equipped with Blackhawk Modifications’ XP140 conversion.

“More useful load means more of what matters to our customers—whether that is passengers, cargo, or the family pet,” noted Clint E. Clouatre, Vice President of Marketing & Sales. “To make this possible, Wipaire’s engineering team thoroughly analyzed and tested the Grand Caravan to approve the higher gross weight. Our robust engineering capabilities exist to deliver more to our customers every day, and we’re excited to make this upgrade available.”

The gross weight increase to 9,187 lbs is available immediately. Eligible aircraft include:
• New production or in-service Grand Caravan EX aircraft on Wipline 8750 floats
• Grand Caravan aircraft modified with the Blackhawk XP140 engine conversion on Wipline 8750 floats

Gross Weight Increase to 8,360 lbs

Wipaire can bring your Cessna 208 on wheels or Wipline 8000 floats up to 8,360 lb gross weight. If your 208 is now certified for 8,000 or 8,200 lb., increasing the gross up to 8, 360 lb. can add one or two more passengers to the manifest — or allow transport of that extra cargo that would have been left behind.

At Wipaire, performance engineering is a way of life. We heartily recommend the STC be added with any engine overhaul or changeover from 600 h.p. to 675 h.p. conversion.

Whether you are flying to a peaceful getaway or to the remote corners of the world, your 8,360 lb. Caravan will deliver you, your passengers, and your payload with ease.

Cessna 206 on Wipline 3450 Floats

Co-Pilot Door

The co-pilot door for the Cessna 206 adds an immense amount of safety and convenience for the front seat passengers of your aircraft by allowing a convenient third way of entering or exiting the aircraft.

This feature is especially desirable when docking on the right side of the aircraft in the case of seaplane operation, and it is also extremely valuable as a way to exit the aircraft in an emergency where the pilot door is jammed or blocked.

The door is manufactured from carbon reinforced composite material and utilizes Cessna manufactured hinges and latches to appear identical to the pilot door. An opera window is installed between the new door and the rear double doors. The door is comprised of an outer aluminum skin and a fiberglass composite inside, with an inner “Royalite”, formed plastic panel.

Portions of your original interior are cut and added to the inside door panel to maintain the inside decor. An armrest and grab handle are also installed. The outside is painted to blend the new door into the fuselage so the outside looks factory original.
