FAA Certification For Cessna Longitude A “Moving Target” Written 11 June 2018

The Wichita Eagle reported that new FAA requirements are stretching the certification date for Textron Aviation’s new Cessna Citation Longitude business jet “farther than the company planned.” Certification has been a “moving target” for the jet, which Textron originally hoped to enter into service in 2017. According to Textron Aviation Senior Vice President of Engineering Brad Thress, Textron has had to work with “10 years of rules changes.” The Cessna Citation Sovereign was the company’s last new aircraft design. According to FAA spokeswoman Elizabeth Isham Cory, new FAA “safety requirements may add additional testing, but that is typical of any new type certification project.”
