1. PLANNING INFORMATION 

A. Effectivity: 

I All SA227 Commuter Category Airplanes. (See also Note 8 of Table 1) 

B. Reason: 

(1) To prevent possible fatigue failure of control column pivot bearing. 

(2) To prevent damage to elevator rod end bearing retainer/dust covers by ensuring 

appropriate hardware configuration for the attachment of the elevator rod assembly 

to the elevator walking beam and control column . 

(3) To prevent possible fatigue failure of the elevator control rod to elevator walking 

beam attach bolt. 

This service bulletin has been completely re-written to address issues and differences 

between the earlier revision of the bulletin, AD 97-02-02, SA227 Commuter Category 

Illustrated Parts Catalog (I PC) Chapters 27-30-30 and 27-30-40, and the SA227 Commuter Category Maintenance Manual Chapter 05-10-00. All changes denoted by revision bar in the left hand margin. 

C. Description: 

This service bulletin addresses three separate issues that are identified herein as 

1.C.(1 ): Control Column Pivot, 1.C.(2): Elevator Rod End, and 1.C.(3): Elevator Rod 

Assembly Attachment Hardware. See Table 1 for compliance requirements. 

(1) Control Column Pivot (see Figure 1) 

To prevent fatigue cracking of the control column pivot bearing, three possible 

actions are required: 

(a) Inspect security of control column roller pivot configuration by application of 

torque to the pivot bearing and ensuring no movement occurs as defined in 

this service bulletin, or; 

(b) Replace the control column pivot bearings and associated hardware with new . 

or newly defined parts and ensure the security of control column pivot by application of torque to the pivot bearing and ensuring no movement occurs as 

defined in this service bulletin, or;

SERVICE BULLETIN 

NOTES: 

<1 > Compliance with this Service Bulletin requires complying with Step 2.D. AND 

with either Step 2.A. or 2.B. or 2.C. 

<2> From time of last replacement 

<3> Incorporation of SB CC7-27-011 complies with Supplemental Inspection 

Document (SID) Supplemental Inspection No. 27-31-01 and eliminates the 

control column pivot bearing time replacement requirement. (Replace pivot 

bearing every 10,000 hours TIS) 

<4> The column pivot configuration must be revised per SB CC7-27-011 prior to 

35,000 hours airplane total TIS or within the next 1,000 hours TIS from the 

effective date of this Service Bulletin, whichever occurs later. 

5 TIS - Time in Service (Flight Hours) 

<6> Performing a replacement bearing initial action within 200 Hours TIS after the 

effective date of this SB has the benefit of eliminating the need for the initial 

torque check and allows for an additional 10,000 hours TIS prior to the need 

for repetitive action. 

<7> There is an additional requirement to comply with SB CC7-27-011 per the 

Supplemental Inspection Document (SID). Therefore, if SB CC7-27-011 is 

not complied with here, compliance with CC7-27-011 will be required per the 

Supplemental Inspection Document (SID). 

<8> SA227-CC/-DC, Airplane SIN 892, 893, 895 and up already comply with the 

intent of Step 2.C. and therefore compliance with NEITHER Step 2.A. nor2.B. 

is required for these airplanes.

CONTROL CABLES DUE TO SPRING TENSION ON CABLES. 

(4) Destroy or permanently mark the removed CF-5/8-S bearings to ensure no future 

use of the bearings. 

(5) Install new CF-5/8-S bearings (or acceptable alternates listed in Step 3) with 

MS21 042L4 nuts and associated washers per Figure 1 using a calibrated torque 

wrench to apply 70.0 in-lbs (+5.0 /-0.0 in-lbs) torque to the nut and bearing. Install 

26-21352-007 doubler assemblies or 26-21352-007P doublers per Figure 1. 

NOTE: The 26-21352-001 doubler assembly is attached to the airplane structure 

using MS21 042L3 nuts, AN3-5A bolts, and AN960-1 OL washers. The 

26-21352-005 doubler assemblies incorporate MS21 073L3 nutplates in 

place of the MS21 042L3 nuts. P/N 26-21352-00?P doubler is available 

with only the roller bearing stud hole drilled and may be used to replace 

either the -001 or -005 doubler assemblies, but requires match drilling of 

the 26-21352-007P doubler to the airframe or removed doubler for the 

AN3-5A attach bolt hole locations (4 places). MS21 073L3 nutplates may 

be installed or MS21042L3 nuts and AN960-10L washers may be used. 

(6) Proceed to Step 2.D. 

C. Control Column Pivot Alternate Design 

This step offers an alternate method of compliance to Steps 2.A. and 2.B. 

(1) Comply with the latest FAA approved revision of Service Bulletin CC7-27-011 . 

(2) Proceed to Step 2.D. 

NOTE: Compliance with Step 2.C. removes the pivot bearing 10,000 hour replacement requirement outlined in Table 1 for Steps 2.A. and 2.B. 

D. Elevator Control Rod 

(1) Remove the elevator control rod attached to the elevator walking beam and control 

column as shown in Figure 2 and as described in the SA227 Commuter Category

(2) Inspect rod end bearing retainer/dust covers for evidence of creasing or other 

damage as shown in Figure 2. If any creasing or other damage is found , remove 

and replace rod end(s). 

(3) Check elevator control rod ends for excessive wear. Grasp the control rod firmly 

in one hand and with the other hand attempt to move the inner ring radially back 

and forth in the bearing face. Any perceptible radial play between the inner ring 

and the race indicates excessive wear and the bearing shall be replaced. 

(4) If the elevator control rod is disassembled to replace one or both of the rod end 

bearings, the control rod must be reassembled with: (a) length adjusted to meet 

elevator control system rigging and travel requirements of SA227 Commuter 

Category MM, Chapter 27-00-00, (b) Both witness holes in control rod covered 

by installed bearings, (c) each bearing installed 90° (+/- 3°) to each other and, (d) 

control rod jam nuts with 40 in-lbs (+/- 5 in-lbs) torque. 

CAUTION: DO NOT ATTEMPT TO TIGHTEN THE CONTROL ROD ASSEMBLY JAM 

NUTS WHILE CONTROL ROD IS INSTALLED SINCE THIS WILL CAUSE 

CREASING OF ROD END BEARING RETAINER/DUST COVER. 

NOTE: To prevent creasing, the rod end retainer/dust covers, the control rod 

length should be adjusted with the jam nuts tightened finger tight and the 

elevator control system travel checked in accordance with SA227 Commuter Category MM, Chapter 27-00-00. Remove the control rod assembly 

and tighten jam nuts by holding the rod ends with a wrench on the flat of 

the bearing housing while torquing the jam nut to 40 in-lbs (+/- 5 in-lbs). 

Ensure that control rod criteria of Step 2.D.(4) is met. 

(5) Reinstall elevator control rod . Use hardware and hardware arrangement as shown 

in FIGURE 2. Replace bolt (PIN NAS6604D31 or previously replaced NAS6604D34 

(with more than 10,000 hours TIS) with a new bolt (PIN NAS6604D34) and install 

a new washer (P/N AN970-4). 

NOTE: Use AN960-416 and/or AN960-41 6L washer(s), shown on either side of 

rod end bearings, as required for clamp up. Ensure that the AN31 0-4 nut 

does not ride on the shank of the NAS6604D34 bolt. 

(6) Adjust elevator and aileron cable tensions and perform elevator and aileron control system travel/adjustment as described in SA227 Commuter Category MM, 

Chapter 27-00-00 and 27-10-00. 

(7) Replace all cockpit furnishings and floorboards removed to accomplish this 

inspection/replacement.
