Gulfstream Disagrees with the FAA

Gulfstream disagrees with the FAA about the regulatory requirements for a hydrophobic water-repellent coating system instead of windshield wipers for the new G150, which is scheduled to be certified next year. The FAA is requiring Gulfstream to meet “special conditions,” a common regulatory method the agency uses when it determines that a particular design feature is “novel or unusual” and not covered in current airworthiness requirements. Gulfstream noted that hydrophobic coatings have a “significant service history” on numerous aircraft and no special conditions applied. The FAA responded simply that those previous certifications “should have included special conditions.”
