AT A GLANCE
Revision 23 adds an installation-specific certification basis and a corresponding POH reference for certain PA-44-180 aircraft with factory-installed G1000 NXi software incorporating a landing gear warning inhibit function and/or wireless local area network capabilities. The listed eligible serial numbers are 4496616, 4496659 and up. No substantive changes were identified to the PA-44-180T provisions or the existing aircraft limits, engine and propeller configurations, or notes.
01
Certification basis added for G1000 NXi software capabilities
PA-44-180, eligible serial numbers 4496616, 4496659 and up, equipped with the Piper factory installed G1000 NXi System upgraded with software incorporating a landing gear warning inhibit function and/or wireless local area network capabilities, as installed by Piper Drawing Number 107700-004 Rev K or later FAA approved revision.
Revision 22 had no separate certification-basis entry for this software configuration. Revision 23 adds one limited to installation-specific items under Piper Drawing Number 107700-004 Rev K or later FAA approved revision. It lists 23.2010, 23.2505, 23.2510 and 23.2605(b)(c) at Amndt. 23 -64, followed by the printed citation “14 CFR Part 23 23.2500(b), 23.2600(b)” at Amndt. 23 -65. This is a configuration-specific addition, not a change to the certification basis for all PA-44-180 aircraft.

POH reference added for the G1000 NXi software configuration
PA-44-180 with the G1000 NXi System software incorporating a landing gear warning inhibit function and/or wireless local area network capabilities, installed by Piper Drawing Number 107700-004 Rev K or later approved revision. The POH entry prints the serial applicability as “SN 4496616, 4496659 & Up and up.”
Revision 23 adds an Equipment-section entry for POH VB-2636, Rev 10 or later, approved September 29, 2026, for the specified G1000 NXi software configuration. Revision 22 contained no corresponding entry. The new serial-number wording is printed as “SN 4496616, 4496659 & Up and up”; the certification-basis entry states “4496616, 4496659 and up.” The existing non-Halon extinguisher POH entry remains substantively unchanged: “Rev 09” becomes “Rev 9,” with the same approval date and applicability. The existing PA-44-180T POH entry and notes are unchanged and move to later pages.
