Has anyone installed these Plane-Power R1224 regulators and removed the diode laden 1960's designed board. If so what paperwork is required and where can I source it? I am a member at CPA and cannot locate any "337 Paperwork" there, Hard to search 337 as our plane keeps coming up too.
In either case I have been chasing ghosts and want to upgrade power system, seems to me that the removal of the old systems and replacement with up to date solid state design makes sense. Just need to stay legal... Thoughts...Help... |

The Plane-Power units are already STC'ed, so no 337 paperwork required. That is a plus*. The wires from the original regulators are re-connected to the new regulators, so the install is very straightforward. The regulator mounting holes for the firewall are different, so most will fabricate a mounting plate out of aluminum to adapt. YMMV. *EDIT - On further review, it appears a 337 form may still be required for the Plane Power regulators. My understanding now is that they would have to be "FAA-PMA" to NOT require a 337 form. Since they are only "STC", they DO require a 337, which requires a cooperative FSDO. Last edited by mshac : 08-30-20 at 01:10 PM. |

So these do not eliminate any of the other systems, just the regulators?

But yes, the rest of the system is unchanged. Dash warning lights still operate, no change to POH, etc. |

The R1224 appears on certain PMA paperwork, but no STC is published for the 337 type A6CE. I’m also chasing ghosts and will be rebuilding the original circuit board And diodes this week. |
