Attention: Bell 407 Operators

LORD Corporation (“LORD”) has developed an improved elastomer (SPE IIA) that has been specifically formulated for helicopter bearing applications. Comparative endurance tests confirm bearings bonded with the improved elastomer will have significant increase in life. SPE IIA was incorporated on the M407 Main Rotor Bearings in September 2014. LORD is offering the improved bearings at no additional cost to customers.

As further demonstration of LORD’s commitment to lowering operator DOC, LORD is extending warranty to align with Bell’s mandatory hub overhaul that occurs at 2,500 hour intervals. Subject to warranty eligibility requirements set forth below, LORD’s warranty covers new and overhauled parts for 3 years / 2500 hours, whichever occurs first the “Enhanced Warranty”). Parts that fail within the warranty period, and meet the warranty eligibility requirements as set forth below, will be replaced free of charge.

Additional information related to the Enhanced Warranty:

  • The Enhanced Warranty applies to parts manufactured after September 1, 2014. This date corresponds to when the SPEIIA elastomer was fully incorporated on the bearings. Customers can use the “cure date” which is stamped on all parts to determine eligibility.
  • The Enhanced Warranty covers damage to the elastomeric bearing only. Damage to the metallic components, including anti-fretting coating - “Blue Coat”, is not covered by the Enhanced Warranty. If such damage is found, LORD will provide a quote for purchase of overhauled part or blue coat repair if appropriate.
  • Three year warranty timeline begins when part is shipped from LORD (or an authorized distributor). Customers submitting a claim based on flight hours must have credible system for tracking flight hours for hub components.
  • Turnaround time: Parts that qualify for the Enhanced Warranty will be replaced with an overhauled part which is typically available from stock.
  • To facilitate efficient processing of your warranty claim, Please contact LORD for Return Material Authorization (RMA). LORD Contact: 814-868-3180 x6238 or Email: repairstation@lord.com.

Enhanced Warranty Terms:

LORD warrants that the products referenced above (“Products”) will be free from any defects in workmanship or material. Such Enhanced Warranty shall extend for a period of (i) three (3) years from the date of shipment of the Product by LORD to Buyer or (ii) 2500 flight hours, whichever occurs first (the “Warranty Period”). The Enhanced Warranty and its Warranty Period shall apply only if all elastomeric parts used in the Main Rotor Hub from which the warranted Product was removed and returned to LORD, are LORD parts. Buyer shall provide LORD with sufficient evidence to prove that all elastomeric parts used in the Main Rotor Hub are LORD parts. Failure to provide such evidence shall result in the Enhanced Warranty for the Product being reduced to the standard warranty for such Product, which has a warranty period of (i) one (1) year from the date of shipment of the Product by LORD to Buyer or (ii) 1000 flight hours, whichever occurs first. In the event a defect in workmanship or material in Product sold develops within the Warranty Period as a result of normal, proper and intended use of the Product, LORD agrees to repair or replace, at LORD's option, the defective Product(s) provided that Buyer gives LORD written notice of any such defect, which such notice is received by LORD within the Warranty Period and which describes the defect. The defective Product(s) shall be delivered to LORD, FOB LORD's facility, at the sole cost and expense of Buyer. REPAIR OR REPLACEMENT OF THE DEFECTIVE PRODUCT(S) IS THE SOLE AND EXCLUSIVE REMEDY OF BUYER WITH RESPECT TO ANY DEFECTIVE PRODUCT(S), AND LORD'S LIABILITY UNDER THIS SECTION IS SUBJECT TO THE PARAGRAPH BELOW. EXCEPT FOR THE WARRANTY SET FORTH ABOVE, LORD DISCLAIMS ANY AND ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. LORD RESERVES THE RIGHT TO MODIFY OR RETRACT THIS WARRANTY AT ANY TIME.

NOTWITHSTANDING ANYTHING TO THE CONTRARY, IN NO EVENT SHALL THE CUMULATIVE LIABILITY OF LORD ARISING OUT OF THE SALE OF PRODUCTS BY LORD TO BUYER UNDER ANY PURCHASE ORDER EXCEED THE AMOUNT PAID BY BUYER TO LORD FOR THE PRODUCTS UNDER SUCH PURCHASE ORDER. LORD SHALL HAVE NO LIABILITY FOR ANY DAMAGE ARISING FROM BUYER'S (i) USE OF A PRODUCT IN A MANNER FOR WHICH IT WAS NOT INTENDED OR (ii) INCORPORATION OF A PRODUCT INTO AN END PRODUCT FOR WHICH IT WAS NOT DESIGNED OR AUTHORIZED FOR USE. IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER FOR ANY INDIRECT, SPECIAL OR CONSEQUENTIAL DAMAGES IN CONNECTION WITH THE SALE OF PRODUCTS BY LORD TO BUYER.
