Rev.9 of D2C-C1 Defect Recording, Reporting, Investigation,

 ✈️ Repetitive Defects – A Small Change in CAR, A Big Shift in Maintenance Thinking

The latest revision of CAR (Section 2, Series C, Part I – Feb 2026) by the Directorate General of Civil Aviation (DGCA), India brings sharper clarity on Repetitive Defects—and it’s more impactful than it may first appear.

🔍 What’s new?
A defect is now considered repetitive if it occurs:
➡️ 3 times within 15 flight cycles
➡️ Despite rectification attempts

But here’s the real game changer 👇

📡 Even if the defect is NOT reported by the crew…
If it is recorded in systems like:

  • Aircraft Health Monitoring (AHM)

  • OEM platforms (e.g., Airbus World)

👉 It MUST still be treated as a reported defect.

⚠️ Why this matters

This shifts maintenance from:
❌ Reactive (fix what is reported)
➡️ To
✅ Data-driven (analyze what the aircraft is telling you)

Repetitive defects are no longer just technical issues—they are:
✔️ Reliability indicators
✔️ Early warning signals
✔️ Potential safety risks

🛠️ Operational Impact

For AMOs and Operators, this means:

  • Stronger defect tracking systems

  • Mandatory Root Cause Analysis (RCA)

  • Better integration of AHM data into maintenance control

  • Closer linkage with Safety Management System (SMS)

👉 Simply replacing components repeatedly is NOT a solution anymore.

💡 Key Takeaway

“Silent defects” are no longer invisible.

If the aircraft reports it—even without a pilot entry—it counts.
And if it repeats—it demands deeper investigation.

📊 In modern aviation:
Safety is no longer event-based…
It is pattern-based and data-driven.

Brake System Cessna 172

                             BRAKE SYSTEM -MAINTENANCE PRACTICES              1. Description and Operation A. The hydraulic brake system is comprised of two master cylinders, located immediately forward of the  pilot’s rudder pedals, brake lines and hoses, and single-disc, floating cylinder brake assemblies located at  each main landing gear wheel. B. The parking brake system is comprised of a pull-type handle and mechanical connections which are  linked to the rudder pedal assembly. Pulling aft on the brake handle applies mechanical pressure to the  rudder pedals, activating the brakes and locks the handle in place. Turning the handle 90 degrees will  release the parking brake and allow for normal operation through the rudder pedals. C. Brake operation is accomplished by pushing on the upper part of each rudder pedal. This motion i...

McCauley Propeller Installation fixed pitch

Image
Propeller Installation for all fixed pitch propellers (except 1A162 model propellers).                   WARNING: MAKE SURE THE MAGNETO IS GROUNDED BEFORE INSTALLING  THE PROPELLER OR CONNECTING EXTERNAL POWER.                NOTE: McCauley recommends that propeller mounting nuts (if applicable) be replaced at each  propeller installation, whenever possible. However, nuts may be reused providing the threads are in good condition and the locking material prevents turning of the nut on the  stud by hand. Propeller mounting bolts must be magnetic particle inspected in accordance  with ASTM E-1444 or replaced whenever the propeller is removed from the engine.                NOTE: The aircraft maintenance manual or STC installation instructions should always be  consulted for any specialized procedures applicable to a specific aircraft....

Cessna 152 Magneto Check

MAGNETO CHECK. NEVER ADVANCE TIMING BEYOND SPECIFICATIONS IN ORDER TO REDUCE RPM DROP. Too much importance is being attached to RPM drop in single ignition. RPM drop on single ignition is a natural characteristic of dual ignition design. The purpose of the following magneto check is to determine that all cylinders are firing. If all cylinders are not firing, the engine will run extremely rough and cause for investigation will be quite apparent. The amount of RPM drop is not necessarily significant and will be influenced by ambient air temperature, humidity, airport altitude, etc. In fact, absence of RPM drop should be cause for suspicion that the magneto timing has been bumped up and is set in advance of the setting specified. Magneto checks should be performed on a comparative basis between individual right and left magneto performance. a. Start and run engine until the oil and cylinder head temperatures are in normal operating ranges. b. Advance engine speed to 1700 RPM. c. Tu...
