Question

List for me the data on Maintenance other than overhaul in the 'Components shall be released in accordance' table.

Answer

Here is a list of **maintenance other than overhaul** for components, along with the corresponding release requirements as per the table in **MLA.502(b)**:

### **Maintenance Other Than Overhaul**
*(Components maintained in accordance with **component maintenance data** issued by the component manufacturer)*

| **Maintenance Type** | **Released Using EASA Form 1** | **Released at Aircraft Level (No EASA Form 1)** |
|----------------------|--------------------------------|-----------------------------------------------|
| **Maintenance other than overhaul** | **Engine-rated** (for engines) or **component-rated** (for other components) maintenance organizations | **(i) Aircraft-rated maintenance organizations; and/or**<br>**(ii) Independent certifying staff** |

### **Additional Notes:**
1. **Aircraft Maintenance Data (if used instead of component data):**
   - For **all components and all types of maintenance** (including maintenance other than overhaul), the release can be done by:
     - **Engine-rated (for engines) or component-rated (for other components) maintenance organizations** (with EASA Form 1).
     - **Aircraft-rated maintenance organizations and/or independent certifying staff** (without EASA Form 1, per MLA.801).

2. **Special Cases (MLA.502(c)):**
   - Components listed in **21.A.307(b)(3) to (b)(6)** can be maintained by **any person/organization** and released with a **""declaration of maintenance accomplished""** (equivalent to EASA Form 1 for installation).

3. **Independent Certifying Staff (GM1 MLA.502):**
   - Can release component maintenance **only if authorized under MLA.201** and competent for the specific task.
   - **Not allowed** for balloons operated under **Subpart-ADD**.
