Models named: 727, 727C, 727-100, 727-100C, 727-200, 727-200F series. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to all The Boeing Company Model 727, 727C, 727-100, 727-100C, 727-200, and 727-200F series airplanes, certificated in any category.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Except as provided by paragraph (h) of this AD, at the applicable time specified in table 1 of paragraph 1.E., “Compliance,” of Boeing Special Attention Service Bulletin 727-55-0094, dated March 21, 2012, do a detailed inspection for any cracking of the elevator rear spar stiffener assembly, and all applicable corrective actions, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 727-55-0094, dated March 21, 2012. Do all applicable corrective actions before further flight. Repeat the inspection thereafter at the applicable time specified in table 1 of paragraph 1.E., “Compliance,” of Boeing Special Attention Service Bulletin 727-55-0094, dated March 21, 2012, except as provided by paragraph (j) of this AD.

Unsafe condition

This AD was prompted by reports of cracks on the elevator rear spar stiffener assembly. We are issuing this AD to detect and correct cracking of the elevator rear spar stiffener assembly, which could adversely affect elevator structural stiffness, which could lead to elevator vibration and possible interference with the tab control rod. These conditions could result in elevator flutter and consequent loss of control of the airplane.

Affected ADs

None.
