10 Plaintiff, ORDER

11 v.

12 EthosEnergy Power Plant Services LLC, et al., 13 Defendants. 14 15 INTRODUCTION 16 Plaintiff Arizona Public Service Company (“APS”) owns and operates the Saguaro 17 Power Plant in Red Rock, Arizona. In April 2018, APS asked a representative of Defendant 18 Advanced Turbine Support Incorporated (“ATS”) to perform a non-destructive 19 examination (“NDE”) of six rows of compressor blades associated with one of the plant’s 20 combustion turbines. An NDE does not require any specific method of examination and 21 instead can encompass several different techniques. Here, two NDE methods are 22 relevant—eddy current testing (“ET”) and ultrasonic testing (“UT”). 23 For reasons that are disputed, ATS used the UT method when examining the blades 24 in rows 1-3 and 6 of the turbine and used the ET method when examining the blades in 25 rows 4 and 5. ATS did not detect any cracks in row 4. However, about a year later, a blade 26 in row 4 broke off and caused approximately $10 million in damage to the turbine. 27 In this action, APS asserts various contract and tort claims against ATS, most of 28 which are premised (in one way or another) on ATS’s failure to use the UT method when 1 examining the blades in rows 4 and 5. Now pending before the Court is ATS’s motion for 2 summary judgment. (Doc. 57.) For the following reasons, the motion is granted in part 3 and denied in part. 4 BACKGROUND 5 I. Relevant Facts 6 The facts set forth below are derived from the parties’ summary judgment 7 submissions and other documents in the record, with any conflicts viewed in the light most 8 favorable to APS. 9 APS “is the largest electric utility in Arizona and owns and operates APS Saguaro 10 Power Plant, a natural gas powered station, located in Red Rock, Arizona.” (Doc. 1-3 at 11 61 ¶ 2; Doc. 18 ¶ 2.) ATS, which is based in Florida, describes itself as “one of the top 12 generator and turbine inspectors in the world.” (Doc. 1-3 at 62 ¶ 6; Doc. 18 ¶ 6.) 13 “On April 10, 2018, a borescope inspection of [APS’s] Siemens Westinghouse 14 501AA combustion turbine . . . performed by [ATS] revealed a liberated diaphragm and 15 significant impact damage at rows 4 and 5 of the compressor.” (Doc. 1-3 at 62 ¶ 9; Doc. 16 18 ¶ 9.) 17 On April 13, 2018, APS hired EthosEnergy Power Plant Services LLC 18 (“EthosEnergy”)—an entity that was originally named as a defendant in this action but has 19 since settled with APS (Doc. 41)—to replace the damaged compressor blades and 20 diaphragms. (Doc. 60-2 at 14.) In the course of its work, EthosEnergy removed the blades 21 in rows 4 and 5 and discovered a cracked blade in row 5. (Doc. 60-5 at 8; Doc. 57-2 at 3.) 22 On or about April 18, 2018, following EthosEnergy’s discovery of the cracked 23 blade, APS representative Mike Stevens (“Stevens”) had a discussion with ATS technician 24 Guillermo Gonzalez (“Gonzalez”), who happened to be on site completing a separate work 25 order, about expanding the scope of the work order to include an NDE of rows 1-6 on the 26 turbine. (Doc. 57-4 at 3 [Gonzalez: “I was inspecting a different unit. I was doing a 27 borescope inspection on a different unit, not that one.”]; Doc. 57-3 at 5 [Stevens: 28 “Guillermo was on site.”].) During his deposition in this case, Stevens provided the 1 following summary of this conversation with Gonzalez: “So I did speak with Guillermo. 2 And I think that’s when we discussed, ‘Hey, we need to do NDE.’” (Doc. 60-5 at 7.) 3 Stevens also “generally” agreed with the description of this conversation appearing in 4 APS’s complaint, which was that APS “requested Guillermo Gonzalez of [ATS] perform 5 a NDE on all compressor blades to discover cracks that may exist in the blades.” (Id. at 6 12.) 7 As a general matter, when determining which type of NDE to perform, ATS relies 8 both on its customers’ preferences and on its own expertise. For example, ATS may “make 9 recommendations [to the customer] based on [its] knowledge” but some customers “tell 10 [ATS] what they want” and/or “ask for recommendations.” (Doc. 60-6 at 10-11.) If ATS 11 disagrees with a customer’s request, ATS “[t]ypically . . . would make a recommendation 12 if it’s something we do have experience with.” (Id. at 11.) Through that recommendation, 13 ATS seeks to “give as much information as [it] can as to why that recommendation is made 14 and allow that customer to make an educated decision on what they want to do.” (Id.) 15 Among the factors ATS considers when deciding which NDE method to employ are the 16 “cleanliness of the component and different issues” like the “surface condition.” (Id. at 17 7.)1 18 On April 19, 2018, Gonzalez emailed a co-worker, ATS inspection specialist Dustin 19 Irlbeck (“Irlbeck”), and asked: “What would the preferred inspection method and 20 procedure be if they request ND[E] of the removed and installed rotor blades?” (Doc. 60- 21 12 at 1.) A few minutes later, Irlbeck responded: “I would recommend phased array UT 22 for all in-situ inspections and PAUT with conventional UT from the bottom for removed 23 blades. We could also perforn [sic] eddy current [ET] on the removed blades.” (Id.)2 For

24 1 There are many different inspection methods, including “liquid penetrant inspections,” “magnetic particle inspections,” “eddy current inspections,” and “ultrasonic 25 inspections.” (Doc. 60-6 at 4.) 26 2 Consistent with his April 19, 2018 email, Irlbeck testified during his deposition that when a blade is removed, ATS’s “best practices” generally involve two methods of 27 examination, ET and UT. (Doc. 60-6 at 9 [“So, again, they complement each other.”].) Irlbeck further explained that when a blade remains inside the compressor (also known as 28 “in situ”), ATS “can’t get to the surfaces because they are below the rotor wheel,” so, “at that point we do the [UT].” (Id.) 1 context, a UT examination is “volumetric,” meaning “you can see discontinuities beneath 2 the surface.” (Doc. 60-6 at 5.) In contrast, an ET examination has an “edge effect,” 3 meaning that it is “sensitive to geometry changes, but it’s still very sensitive to small 4 discontinuities at and near the edges.” (Id. at 6.) As Irlbeck explained during his deposition 5 in this case, the risk with the ET method is that when it is performed near the edges of a 6 blade, it “sometimes gets blended in with the geometry indication so that the inspector has 7 to be able to see that.” (Id. See also id. at 8 [explaining that UT can “see deeper into a 8 component” whereas ET “has more of a skin effect”].) 9 One of the disputed issues in this case is whether Irlbeck’s recommendation to 10 Gonzalez—that is, to use the UT method when examining all six rows of blades—was ever 11 relayed to Stevens. Irlbeck testified that he never provided this recommendation to Stevens 12 “in writing” and also did not, to his “best recollection,” ever speak with Stevens about the 13 recommendation. (Doc. 60-6 at 13.) Gonzalez, too, stated “I don’t know” when asked to 14 identify “what recommendations, if any, [ATS] made to Mike Stevens or anyone else at 15 APS Saguaro about which nondestructive examination should be done on this unit.” (Doc. 16 57-4 at 4.) Finally, Stevens’s testimony on this topic was somewhat equivocal and 17 inconsistent. At one point during his deposition, Stevens stated “Not that I recall” when 18 asked whether there was “any discussion . . . of the benefits . . . and drawbacks of both 19 methods at that point in time.” (Doc.
