The ASI/DAR issues the special airworthiness certificate for operating the amateur-built aircraft.

But, it is general enough in scope to show that the certification inspection is not to be a detailed Annual/100 hour type inspection since the builder/applicant has already declared that the aircraft is 'airworthy' by signing the application for the airworthiness certificate. It is not intended to be all-inclusive for every variation of amateur-built aircraft. (9) Gyroscopic direction indicator (directional gyro or equivalent).Īs far as converting an airplane from VFR to IFR, the Type Certificate Data Sheet (TCDS) must specify that the airplane is designed for IFR flight, and then you could add the missing equipment to make it qualify.This document has been developed for use by Aviation Safety Inspectors (ASIs) and Designated Airworthiness Representatives (DARs) as a basic inspection guideline for certification of amateur-built aircraft.

(8) Gyroscopic pitch and bank indicator (artificial horizon). (7) Generator or alternator of adequate capacity. (6) A clock displaying hours, minutes, and seconds with a sweep-second (5) Sensitive altimeter adjustable for barometric pressure. Installed in accordance with §29.1303(g) of this chapter. (ii) Rotorcraft with a third attitude instrument system usable throughįlight attitudes of ☘0 degrees of pitch and ☑20 degrees of roll and

(i) Airplanes with a third attitude instrument system usable throughįlight attitudes of 360 degrees of pitch and roll and installed inĪccordance with the instrument requirements prescribed in §121.305(j) (3) Gyroscopic rate-of-turn indicator, except on the following (2) Two-way radio communication and navigation equipment suitable for Section, and, for night flight, instruments and equipment specified in (1) Instruments and equipment specified in paragraph (b) of this For IFR flight, the following instruments airworthiness certificates: Instrument and equipment requirements. §91.205 Powered civil aircraft with standard category U.S. The installed equipment required for IFR flight (beyond that required for VFR flight) is listed in 91.205(d) and is mostly equipment used to communicate with ATC and to maintain control of the airplane when flying without visual reference to the ground (so no navigation equipment is specified): It is prohibited, must be established appropriate to the installed Icing) to which the operation of the airplane is limited or from which VFR, IFR, day or night) and the meteorological conditions (e.g. For a normal category airplane certified under 14 CFR 23, it basically says that it must be 'established appropriate to the installed equipment': As you say, the FAA certifies an aircraft for certain 'kinds of operation'.
