Attempts thus far to resolve the ongoing CRJ100/200 flap failure problem has led to manufacturer Bombardier endorsing an interim fix while at the same time engaging an airframe expert (US manufacturer Eaton) to design a permanent fix (see acc&inc table 14 Jan entry for Flt SKW5808 flap failure). SkyWest has indicated it has experienced "some challenges and difficulty" in implementing the flap fix currently available, as called out in the Airworthiness Directive (i.e. to clean, lubricate, calibrate, seal and test at a cost of $2,160 per regional jet). The AD had a target date for operator implementation of 03 Jan. The regulator in October 2007 proposed amending the August AD on CRJ100/200 flaps to include requirements that operators of the type in the USA provide simulator training covering reduced- or zero-flap landings for pilots, and perform several additional maintenance actions. It's generally acknowledged that moisture ingress during cold weather operations is the nub of the problem. According to Bombardier, Eaton's design modification task, set to begin soon, is being done "in the spirit of continuous improvement" and should enhance reliability - particularly for cold weather operations.

The FAA recently certified ARINC Incorporated to issue aircraft STCs and perform STC-related aircraft service and modification work under the FAA's new Organization Designation Authorization (ODA) program. This New FAA Certification Program will ultimately replace the DAS System (Designated Alteration Station). ODA rules permit a greater delegation of functions related to engineering, manufacturing, operations, airworthiness, and maintenance. In addition to STC designees, DOA, SFAR36, PC ODAR, PMA ODAR, and Operator/145 ODAR designees will be required to achieve ODA designation by November 2009. The FAA may issue an ODA as needed to any organization with sufficient facilities, resources, personnel, experience with FAA requirements and procedures, and experience to perform the functions. The organization is named ODA Holder, and one or more specific units of suitably trained and experienced personnel within the organization can perform delegated work.
