Is AD 2016-22-16 a recurring Airworthiness Directive?

Yes — AD 2016-22-16 requires a repetitive inspection every 660 hours. Next-due depends on the aircraft's time in service.

Airworthiness Directive 2016-22-16

Q: Which aircraft does AD 2016-22-16 apply to?

AD 2016-22-16 applies to Bombardier — models CL-600-2C10, CL-600-2D15, CL-600-2D24, CL-600-2E25, CL-600. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Bombardier, Inc. Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, and 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 AD was prompted by a determination that wear and possible leakage of the high-pressure seal in the cylinder of the No. 3 hydraulic system reservoir could occur and cause high hydraulic fluid temperature and/or prevent the system from reaching normal operating pressure. This AD requires repetitive operational checks for wear and leakage of the high-pressure seal in the cylinder of the reservoir of the No. 3 hydraulic system, and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect every 660 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Serial-conditional — narrows to serials 10002–10999, 15001–15990, 19001–19990.

Part-conditional — 960450-1.

Applies only to airplanes equipped with No. 3 hydraulic system reservoir having part number 960450-1. CL-600-2C10 = Regional Jet Series 700/701/702; CL-600-2D15 = Series 705; CL-600-2D24 = Series 900; CL-600-2E25 = Series 1000.

Whether AD 2016-22-16 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
