Department of Transportation November 17, 2017 – Federal Register Recent Federal Regulation Documents

To standardize manufacturer and reconditioner approvals, PHMSA is proposing to terminate any M-number and R-number approvals that were previously issued without an expiration date. The termination of these approvals will take effect one year from the publication date of this notice. Approval holders must either show cause why their approvals should not be terminated or apply for a modification of their approval prior to the effective date to avoid termination. Once terminated, requests for reconsideration of the termination must be submitted within 20 days of the date of termination.

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), CL-600-2D15 (Regional Jet Series 705), CL-600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional Jet Series 1000) airplanes. This proposed AD was prompted by several incidents of electrical shorting and sparks caused by de-icing fluid leaks between flight deck windshields and side windows. This proposed AD would require water spray tests and general visual inspections for water in the flight compartment, and water removal and sealant application if necessary. We are proposing this AD to address the unsafe condition on these products.
