Adding IFR Plane Certification To Planes Without It
Michael Adams wrote:
What does the FAA say about adding IFR certification to planes which do not have it? Can IFR be added to any plane, or does it have to have some sort of "pre-cerfication" by the manufacturer for make and model? This question came up, because I have seen IFR added to a few aerobatic models, presumably for "emergency IFR". I know for helicopters, you can't add IFR unless it meets certain stability requirements. I wasn't sure about planes. "adding IFR certification"? please explain... rats...my copy of the FAR is at the hangar. but if I remember correctly, the requirements include static/pitot check every 24 months mode c transponder communication equipment adequate to talk with ATC (radio that has .x25) navigation equipment as appropriate (can't remember the exact minimum but I think it's 1 VOR receiver and indicator...is ILS required? Possibly an ADF/DME in addition...) |

All that I have seen specify a placard in the airplane that says something like "This Aircraft Is Certified for the following conditions: Day - Night - VFR - IFR: If properly equipped". (That was the placard language from a C-152, anyway.) For homebuilts, well, the way it was explained to me by the friendly Van's people is that the builder cerifies everything about the aircraft, so they can specify anything they want, assuming proper equipment as you noted in the reply below. -- Aaron Coolidge |

This question came up, because I have seen IFR added to a few aerobatic models, presumably for "emergency IFR". As I understand it, the type certificate for a given model indicates approval for flight in IFR conditions. The vast majority of certificated GA aircraft are so approved. Some specialty aircraft, like purely aerobatic models, might not be certified for IFR -- I really don't know. In any case, I suspect that adding IFR approval to an aircraft whose type certificate lacks it would probably require at least an STC. Now, beyond type certificate approval, Part 91 IFR operation in an airplane carries certain minimum equipment requirements AND a static system/altimeter check within the preceding 24 months. Sometimes that static system/altimeter test is (erroneously) referred to as "IFR certification". As I said, most GA airplanes are approved for IFR operations, and most manufactured within the past 40 years or so are equipped with basic IFR instruments (sensitive altimeter, gyro compass, AI, and rate of turn indicator). So, what generally is required to make a previously VFR-only airplane legal for IFR is, in most cases, addition of required avionics if not already installed and successfully passing a static system/altimeter test. Minimum avionics requirements are 2-way VHF com and nav gear suitable for facilities that will be used. Does this answer your questions? -- -Elliott Drucker |

With regard to Day/Night IFR/VFR required placarding, what steps do
you need to take to have the placard installed on an airplane that does not already have the placard (A&I signoff??)? This has come up at checkride time with another airplane on the ramp, but I don't know what the resolution was. Jesse N4372X |

Aircraft that don't have the required placards aren't airworthy. Someone, either an A&P (doesn't need to be an IA) or perhaps the pilot-owner (acting under the preventive maintenance sections of Part 43 Ap. A) needs to put it write and make the appropriate log book entries. |

Michael,
one example for a non-IFR-certified aircraft would be the Diamond DA-20 Katana. It lacks the lightning protection needed for IFR certification. -- Thomas Borchert (EDDH) |

"M" wrote in message om... That VOR needs a VOR check in the past 60 day with a log entry in the aircraft. You mean 30 days, right? |
