SERVICE BULLETIN M20-345A
Mooney M20A · Service Bulletins
Overview
This Service Bulletin M20-345A, issued by Mooney International Corporation on December 13, 2022, addresses the replacement of hybrid elevator weights on specific Mooney aircraft models. The bulletin primarily affects M20F aircraft with smooth skin elevators and outlines the procedures for inspecting and replacing the hybrid balance weights (P/N 430018-1) with solid lead weights (P/N 430016-7). The bulletin is crucial for ensuring the safety and airworthiness of the affected aircraft, as it addresses issues related to galvanic corrosion and structural integrity of the elevator balance weights. Compliance is required before the next flight and during annual inspections until the replacement is completed.
- Affected models include M20C, M20D, M20E, M20F, and M20G with serial numbers 680170 or earlier.
- Replace hybrid elevator weights (P/N 430018-1) with solid lead weights (P/N 430016-7).
- Maximum allowable static unbalance moment: 22.0 inch/pounds (1.725 pounds) at 12.75 inches aft of hinge line.
- Minimum allowable static unbalance moment: 20.00 inch/pounds (1.57 pounds) at 12.75 inches aft of hinge line.
- Inspection for cracks or damage to the hybrid weights is mandatory before flight.

Introduction
The bulletin discusses the identification and replacement of hybrid elevator balance weights (P/N 430018-1) found in specific M20F aircraft. These weights have been reported to develop galvanic corrosion, leading to potential safety issues. The bulletin mandates the removal of these weights and their replacement with solid lead weights (P/N 430016-7).
Compliance
Compliance with this bulletin is required before the next flight and during annual inspections until the hybrid weights are replaced. The bulletin emphasizes the importance of inspecting the elevator balance weights for signs of damage or corrosion.
Inspection Procedures
Pilots and maintenance personnel are instructed to inspect the elevator flight control for the presence of the hybrid weight. If the hybrid weight is found and shows no signs of damage, the aircraft may continue to fly. If cracks are present, the aircraft must not be flown.
Weight Replacement
The bulletin provides detailed steps for replacing the hybrid weights with solid lead weights. This includes disconnecting the elevator push-pull tubes, removing the elevator, and ensuring proper balancing of the elevator after installation of the new weights.
Balancing Specifications
When balancing the elevators with the new weights, the maximum allowable static unbalance moment is 22.0 inch/pounds (1.725 pounds) at 12.75 inches aft of the hinge line, and the minimum is 20.00 inch/pounds (1.57 pounds). Proper balancing is critical for safe aircraft operation.
Return to Service
After completing the replacement and inspection, the aircraft must be checked for full control travel, proper rigging, and security of mounting before being returned to service. Documentation of compliance must be completed and submitted to Mooney International.
Safety notes
- If cracks are present in the hybrid weight, do not fly the aircraft until the weight is replaced.
- Use proper handling and personal protective equipment (PPE) when dealing with lead weights.

AFFECTED: TIME OF Before Next Flight and Annual Inspection until the 430018-1 weights are replaced. COMPLIANCE: INTRODUCTION: There are specific M20F aircraft with smooth skin elevators 430000-503 (LH), 430000-504 (RH) identified with 9 rib lines, that utilized a hybrid material elevator balance weight. These weights (P/N 430018-1) are identified by the center plug made of chromoly tubing and lead running through the full width of the balance weight. During routine maintenance at an Authorized Mooney Service Center, the elevator balance weights were found to have developed galvanic corrosion, visible signs of the weight is cracked and displaced severely. There have been several instances of this anomaly reported only on M20F aircraft using this hybrid balance weight. Based on original service center discoveries and field reports from the initial released version of this ser- vice bulletin, Mooney engineering requests that all 430018-1 hybrid weights be removed and re- placed with the 430016-7 lead weights. The 430018-1 balance weight is similar in size and shape (but not in weight) to the 430016-7 bal- ance weight. It is possible the 430018-1 balance weight has been installed in the field repairs on models M20C, M20D, M20E and M20G aircraft. This is the reason Mooney Engineering has de- termined that this will require an inspection, and if a 430018-1 weight is installed, perform proce- dures as described in this Service Bulletin M20-345A. The attached compliance card needs to be filled out and returned to Mooney International Corporation upon completion of this Service Bulletin M20-345A. INSTRUCTIONS: Read entire procedures before beginning work. STEP 1 - Inspection of Elevator Flight Control for 430018-1 Hybrid Weight: MODEL ELEVATOR P/N WEIGHT P/N M20C M20D 430000-5 (LH) 430000-6 (RH) M20E 430016- 7 M20G M20F 430000-503 (LH) 430000-504 (RH) 430018-1 or 430016-7 430000-503 (LH) 430000-504 (RH) ORIGINAL EQUIPMENT AS DELIVERED FROM THE FACTORY 1.1. Inspect of both elevators for the presence of a hybrid weight, part number 430018-1. The hybrid weight has a steel sleeve at its center plug. Inspect the weight visually and with a neodymium magnet on both sides of the balance weight assembly where the center plug is exposed, to see if the magnet sticks to the steel insert of the hybrid weight as indicated in Figure SBM20-345-1 and SBM20-345-2. 1.2. If the weight is determined not a 430018-1 balance weight, the aircraft may be flown and no further inspections are required for Service Bulletin M20- 345A. Record this inspection in Aircraft Log Book. 1.3. If the balance weight is determined to be a hybrid weight 430018-1, and initial inspection shows no sign of cracking or chipping, Continue to STEP 2 for further action. 1.4. If the balance weight is determined to be a 430018-1, and cracks are present DO NOT FLY, Continue to STEP 3.
