AD 2008-06-28 R1 currently requires you to do a check of the maintenance records and inspection of the PFD (if necessary) to determine if an affected serial number PFD is installed and incorporate (if necessary) operational limitations. Since we issued AD 2008-06-28 R1, Avidyne developed a factory service procedure that will correct the problems on these Avidyne PFDs and also factory serviced certain serial number PFDs. Consequently, this proposed AD would retain the actions from AD 2008- 06-28 R1 until the affected PFD is factory serviced; add the actions of a label or marking check, an air data system performance verification test, and (if necessary) replacement of the PFD and factory servicing of the failed PFD; and reduce the serial number applicability from that of AD 2008-06-28 R1. We are proposing this AD to prevent certain conditions from existing when PFDs display incorrect attitude, altitude, and airspeed information. This could result in airspeed/ altitude mismanagement or spatial disorientation of the pilot with consequent loss of airplane control, inadequate traffic separation, or controlled flight into terrain. 73 FR 67429 https://www.govinfo.gov/app/details/FR-2008-11-14/E8-27082 E8-27082 fr14no08-37 RIN 2120-AA64 4910-13-P Docket No. FAA-2008-1210 Directorate Identifier 2008-CE-047-AD https://www.govinfo.gov/app/details/FR-2008-11-14/E8-27082 https://www.govinfo.gov/content/pkg/FR-2008-11-14/html/E8-27082.htm https://www.govinfo.gov/content/pkg/FR-2008-11-14/pdf/E8-27082.pdf Air Transportation Aircraft Aviation Safety Incorporation by Reference Safety 5 p. 67429 67433 73 FR 67429 Title 14 Part 39 14 CFR Part 39 RIN 2120-AA64 Airworthiness Directives; Avidyne Corporation Primary Flight Displays (Part Numbers 700-00006-000, -001, -002, -003, and -100); Federal Register Vol. 73, Issue PRORULE E8-27082 DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 2009-01-13 Docket No. FAA-2008-1210 Directorate Identifier 2008-CE-047-AD 4910-13-P E8-27082 Notice of proposed rulemaking (NPRM).

We propose to supersede Airworthiness Directive (AD) 2008-06- 28 R1, which applies to certain Avidyne Corporation (Avidyne) Primary Flight Displays (PFDs) (part numbers (P/Ns) 700-00006-000, -001, -002, -003, and -100) that are installed on airplanes. AD 2008-06-28 R1 currently requires you to do a check of the maintenance records and inspection of the PFD (if necessary) to determine if an affected serial number PFD is installed and incorporate (if necessary) operational limitations. Since we issued AD 2008-06-28 R1, Avidyne developed a factory service procedure that will correct the problems on these Avidyne PFDs and also factory serviced certain serial number PFDs. Consequently, this proposed AD would retain the actions from AD 2008- 06-28 R1 until the affected PFD is factory serviced; add the actions of a label or marking check, an air data system performance verification test, and (if necessary) replacement of the PFD and factory servicing of the failed PFD; and reduce the serial number applicability from that of AD 2008-06-28 R1. We are proposing this AD to prevent certain conditions from existing when PFDs display incorrect attitude, altitude, and airspeed information. This could result in airspeed/ altitude mismanagement or spatial disorientation of the pilot with consequent loss of airplane control, inadequate traffic separation, or controlled flight into terrain.
